Feature request: proper MDX support

[razcore-rad]

Since I work with MDX files daily it's really a pain not to have proper highlighting support for custom HTML/JSX elements & comments like {/* comment /*}.

I know MDX was added using the standard Markdown tree-sitter:

• languages: add mdx to markdown filetypes #11122
• languages: add mdx to markdown filetypes #11122 (comment)

Since then I've seen references to:

• https://github.com/srazzak/tree-sitter-mdx
• https://github.com/wooorm/markdown-rs

See tree-sitter-grammars/tree-sitter-markdown#137 (comment)

I have 0 experience with tree-sitter & grammars and all that jazz, I'm hoping to catch the attention of someone that knows their way around it. I can't even asses if these solutions are acceptable or not, but it'd be great to have proper highlighting since MDX is pretty popular these days.

Thanks!
