* build(tree-sitter): update javascript, typescript and tsx
* update revision of tree-sitter parsers for these languages.
* rename `?.` to `optional_chain`, introduced in tree-sitter/tree-sitter-javascript@186f2adbf7.
* fix(highlight): change jsx queries to match latest tree-sitter
Latest tree-sitter/tree-sitter-javascript@bb1f97b643 added some breaking changes that broke highlighting.
* Remove some queries with `nested_identifier`.
* Remove deprecated `jsx_fragment` from indent query.
* Count `</` and `/>` as a single token.
JavaScript queries now contain a few lines that prevent them from
being used whole-sale in typescript with `; inherits: javascript`.
Here we follow nvim-treesitter's way of using a fake 'ecma' language
as a common base for JavaScript and TypeScript to share as much as
we can.
