(feat!)capture: unify template variables

Instead of using various capture template variables, like
org-roam-dailies-capture-templates or org-roam-capture-ref-templates,
just use org-roam-capture-templates for everything.

From now on, each individual template will able to optionally specify a
more detailed context for which they're dedicated for, using :kind and
:action properties. Both of them accept either, a symbol or a list of
symbols.

If it's a list, then it can optionally start with :not symbol to
indicate inverse logic, otherwise it will act akin to memq. If it's a
symbol, then it will work akin to eq, but with support for special 'any
value, which indicates that it will work in any contexts; 'any can be
also used inside of the list based values.

Org-roam and the built-in extension will provide the following contexts:
- :action {capture,goto,any}
- :kind {normal,daily,protocol,any}
but third party extensions / users can easily extend them for their own
needs.

If :action isn't specified it will implicitly default to 'capture, while
:kind will default to 'normal contexts.

BREAKING CHANGE: org-roam-dailies-capture-templates and
org-roam-capture-ref-templates are now removed in the favor of unified
approach.

+### Using Doom Emacs
+<details>
+<summary>Toggle instuctions</summary>
+
+Doom's `:lang org` module comes with support for `org-roam`, but it's not
+enabled by default. To activate it pass `+roam2` flag to `org` module in your
+`$DOOMDIR/init.el` (e.g. `(org +roam2)`), save the file and run `doom sync -u`
+in your shell.
+
+To provide better stability, Doom pins the package to a specific commit. If you
+need to unpin it *(not recommended doing that, request Doom to bump the package
+instead)* use the next in your `packages.el`:
+
+```emacs-lisp
+(unpin! org-roam)
+```
+
+If for some reasons you want to use a different recipe for `org-roam`, you can
+use the next form in your `packages.el` to install the package from a recipe
+repository (e.g. MELPA):
+
+```emacs-lisp
+(package! org-roam)
+```
+
+You can pass `:pin "commit hash"` to pin the package to a specific commit.
+
+With the next sample you can install the package directly from the source
+repository:
+
+```emacs-lisp
+(package! org-roam
+  :recipe (:host github :repo "org-roam/org-roam"
+           :files (:defaults "extensions/*")))
+```
+
+And if you plan to use your own local fork for the development or contribution,
+the next sample will get you there:
+
+```emacs-lisp
+(package! org-roam
+  :recipe (:local-repo "/path/to/org-roam-fork"
+           :files (:defaults "extensions/*")
+           :build (:not compile)))
+```
+</details>
+
+### Without a package manager
+<details>
+<summary>Toggle instructions</summary>
+
+To install the package without using a package manager you have the next two
+options:
+
+1. Install the package by cloning it with `git` from the source repository.
+2. Or install the package by downloading the latest [release
+   version](https://github.com/org-roam/org-roam/releases).
+   
+In both of the cases you will need to ensure that you have all the required
+dependencies. These include:
+
+- dash
+- f
+- s
+- org (9.4 is the minimal required version!)
+- emacsql
+- emacsql-sqlite
+- magit-section
+- filenotify-recursive
+
+After installing the package, you will need to properly setup `load-path` to the
+package:
+
+``` emacs-lisp
+(add-to-list 'load-path "/path/to/org-roam/")
+(add-to-list 'load-path "/path/to-org-roam/extensions/")
+```
+
+After which you should be able to resolve `(require 'org-roam)` call without any
+problems.
+
+Org-roam also comes with `.texi` files to integrate with Emacs' built-in Info
+system. Read the manual to find more details for how to install them manually.

+
+;;; Commentary:
+;;
+;; This extension provides functionality for creating daily-notes, or shortly
+;; "dailies". Dailies implemented here as a unique node per unique file, where
+;; each file named after certain date and stored in `org-roam-dailies-directory'.
+;;
+;; One can use dailies for various purposes, e.g. journaling, fleeting notes,
+;; scratch notes and whatever else you can came up with.
+;;
+;; To add new capture templates dedicated for dailies, specify ":kind daily" for
+;; each of such template in `org-roam-capture-templates', e.g.
+;;
+;;   (setq org-roam-capture-templates
+;;         '(("d" "daily" entry "* %?" :kind daily
+;;            :if-new (file+head "%<%Y-%m-%d>.org"
+;;                               "#+title: %<%Y-%m-%d>\n"))))
+;;
+;; Note that in order for your daily files to properly integrate with the
+;; calendar, each daily file should be named with a format understood by
+;; `org-parse-time-string'.

-;;; Commentary:
-;;
-;; This library provides `org-roam-doctor', a utility for diagnosing and fixing
-;; Org-roam files. Running `org-roam-doctor' launches a list of checks defined
-;; by `org-roam-doctor--checkers'. Every checker is an instance of
-;; `org-roam-doctor-checker'.
-;;
-;; Each checker is given the Org parse tree (AST), and is expected to return a
-;; list of errors. The checker can also provide "actions" for auto-fixing errors
-;; (see `org-roam-doctor--remove-link' for an example).
-;;
-;; The UX experience is inspired by both org-lint and checkdoc, and their code
-;; is heavily referenced.

+
+Notes taken in v1 are incompatible with v2, but you can upgrade
+them to the v2 format via a simple command. To migrate your
+notes, first make sure you're on at least Org 9.4 (check with
+C-h v org-version) and set your org-roam-directory to your notes:
+
+(setq org-roam-directory \"path/to/org/files\")
+
+then, run:

+  M-x org-roam-migrate-wizard
+
+If you wish to stay on v1, v1 is unfortunately not distributed on
+MELPA. See org-roam/org-roam-v1 on GitHub on how to install v1.
+
+If you've gone through the migration steps (if necessary), and
+know what you're doing set `org-roam-v2-ack' to `t' to disable
+this warning. You can do so by adding:
+
+(setq org-roam-v2-ack t)
+
+To your init file.

-;; 2. "roam-ref": This protocol creates or opens a note with the given REF
