Henrik Lissner bd0bee92cc feat!(javascript): add treesit support
BREAKING CHANGE: This commit removes a number of core packages and
features from this module and only replaces a handful of them, so that
we can lean more on LSP and tree-sitter. To be specific:

- We used to rely on `rjsx-mode` (derived from js2-mode) for total
  JS/JSX support (though imperfect; Emacs was starved for options at the
  time). This has now been replaced with `js-ts-mode` (built-in after
  Emacs 29), falling back to `js-mode` (very rudimentary, but a decent
  fallback).
- This also meant the removal of `js2-mode`, which `skewer-mode`,
  `js2-refactor`, and `xref-js2` depended on, so those were removed
  too, and have *somewhat* been replaced with LSP integration (offers
  jump-to-definition/references and *some* refactoring actions, but no
  replacement for skewer's functionality).
- Typescript support no longer relies on the jury-rigged, web-mode-derived
  major mode (because TSX support in the upstream `typescript-mode`
  isn't great). We now use `typescript-ts-mode` (built-in into Emacs
  29.1+), falling back to `typescript-mode`.
- JSX/TSX support now *requires* tree-sitter (and Emacs 29.1+), where
  `tsx-ts-mode` is available and outshines all the alternatives (at the
  time of writing).

Due to the absolute chaos that is webdev, this module sacrifices some of
the graceful-degradation I've implemented for other modules and creates
a hard requirement on tree-sitter and Emacs 29.1+ for JSX/TSX. It still
tries to degrade gracefully for plain JS and TS, but the module's doctor
and docs will actively recommend tree-sitter.
