refactor!(org): remove org-roam v1

BREAKING CHANGE: This finally removes org-roam v1, which has been
deprecated for nearly 5 years (since 5ef733b). Most users should already
be on it. v2 has a migration wizard for anyone still on v1, which will
kick in if it detects a v1 roam db.

-*** Should I go with =+roam= (v1) or =+roam2= (v2)?
-Long story short: if you're new to [[doom-package:org-roam]] and haven't used it, then you should
-go with [[doom-module:+roam2]]; if you already have an ~org-roam-directory~ with the v1 files in
-it, then you can keep use [[doom-module:+roam]] for the time being, but it will eventually be
-removed, so you should [[https://www.orgroam.com/manual.html#How-to-migrate-from-Org_002droam-v1_003f][migrate]] at your earliest convenience.

-V1 isn't actively maintained anymore and is now basically EOL. This means that
-the feature disparity between the both will continue to grow, while its existing
-bugs and problems won't be addressed, at least by the main maintainers. V2 can
-be considered as a complete rewrite of the package so it comes with a lot of
-breaking changes.

-*** Migrating your existing files from v1 (=+roam=) to v2 (=+roam2=)
-V2 comes with a migration wizard for v1 users. It's new, which means issues can
-appear during the migration process. Because of that, *don't forget to backup*
-your ~org-roam-directory~ before attempting to migrate.
-
-In order to migrate from v1 to v2 using Doom follow the next steps:
-1. Enable [[doom-module:+roam2]] flag (and disable [[doom-module:+roam]] if it was previously enabled) in your
-   =init.el=.
-2. Ensure your ~org-roam-directory~ points to a directory with your v1 files.
-3. Run ~$ doom sync -u~ in your shell.
-4. Restart Emacs (if it was previously opened) and run ~org-roam-migrate-wizard~
-   command (~M-x org-roam-migrate-wizard RET~). The wizard will automatically
-   attempt to backup your previous ~org-roam-directory~ to =org-roam.bak=, but
-   just in case backup it yourself too.
-4. After the wizard is done you should be good to go. Verify the integrity of
-   your data and whether it did everything as expected. In case of failure
-   [[https://github.com/org-roam/org-roam/issues][report]] your issue.
