Use tree-sitter-languages to reduce dependencies.

Tree-sitter-languages conveniently exposes all languages at once, removing the need to depend on language specific tree-sitter extensions.

Thanks for the PR @fvisin !
I noticed that the tree_sitter_language package (Link) is marked as unmaintained:

This library is unmaintained, as an alternative you can use .. tree-sitter-language-pack: https://github.com/Goldziher/tree-sitter-language-pack

Should we consider switching to tree-sitter-language-pack instead?

Ah, bummer! Sorry I didn't realise that it was unmaintained. Then yes, absolutely, let's use the updated fork instead!
