Closes #12211

What does this PR do?

Adds syntax highlighting to jsx and tsx code blocks within markdown by adding JSX and TSX parsers to parser-config.ts.

How did you verify your code works?

Ran bun dev with a session that outputs jsx and tsx code blocks.

Remarks

Remarks:

• tree-sitter-javascript.wasm seems to be able to handle jsx
• tree-sitter-typescript highlights seems incomplete
• Maybe it's better to map tsx and jsx to markdown's infoMapString within @opentui/core.

jsx and tsx files seem to be highlighted when part of Write tool output, so this might be only an issue for markdown-injected jsx and tsx.
