update tree-sitter-javascript and tree-sitter-typescript

[m4rch3n1ng]

i only updated to the latest 0.23 tree-sitter-javascript commit, as that is what tree-sitter-typescript depends on currently. this also adds the dedicated grammars for gjs, as that was removed from the javascript grammar.

notable changes:

• tree-sitter/tree-sitter-javascript@84c57ee renamed the (function) node to (function_expression)
• tree-sitter/tree-sitter-javascript@a2ef079 removed support for the gjs and gts templating languages in favor of dedicated grammars at https://github.com/ember-tooling/tree-sitter-glimmer-javascript/ and https://github.com/ember-tooling/tree-sitter-glimmer-typescript/
