bug: README: inline latex is not listed in Extensions

[jmtd]

Did you check existing issues?

• [ ] I have read all the tree-sitter docs if it relates to using the parser
• [X] I have searched the existing issues

Tree-Sitter CLI Version, if relevant (output of tree-sitter --version)

v0.22.6 (via nvim 0.10.0)

Describe the bug

The markdown parser is described as "…CommonMark Spec, but some extensions…are also included.".

One of those extensions must be Inline latex, as pictured in the example screenshot. This isn't part of CommonMark, but is also not listed in the Extensions list.

It'd be nice to have a linked spec for the inline latex, to (easily) understand what it can and can't do. Is it from Pandoc?

Thanks!

I expect that is just injecting the latex parser into a latex_block node.
