Enable multiple treesitter grammars in `shell.nix`

[armijnhemel]

I have trouble figuring out how to enable multiple grammars for treesitter, which I want to use (preferably with a shell.nix as that is what I am comfortable with).

I would appreciate some advise for both a "clean" repository as well as for this one:

@armijnhemel Please repost your question on the NixOS Discourse, as that may get you the answer more quickly.

Hey, @armijnhemel. You still need help with this? I'll also try to PM you.

Yes. I sent you a reply a few days ago, which I will quote here:

"The ideal outcome for me wouldn't just be a fix for my particular problem, but also some docs that can for example be shared on the NixOS wiki, or some expressions in nixpkgs."

We've implemented a hacky solution that should unblock you, but it only works with tree-sitter (python binding) < 0.22.0

Here's the link: https://github.com/ngi-nix/nixpkgs/blob/c06e35046b115819be5e6350e5485135605df942/pkgs/development/python-modules/tree-sitter-languages/default.nix
