Upstream to nvim-treesitter

[PgBiel]

Hello,

I believe it would be nice if this grammar could be made available by default on nvim-treesitter, which would greatly simplify the neovim setup mentioned in the README, as, at least for treesitter syntax highlighting, it'd consist only of :TSInstall c3 (for example). In addition, this would ensure (in my case) that the built grammar is officially shipped by nixpkgs (and perhaps other package managers).

Seems like there is some prior work here, but unfortunately it didn't move forward: nvim-treesitter/nvim-treesitter#7271

Ideally, you could assign yourself as the maintainer and make a PR to nvim-treesitter on every release, but we could keep this issue open to see if others would be willing to do that as well, if that wouldn't be desired or possible.

I do maintain the highlight definitions from time to time but I'm only an occasional nvim user myself, so I'm not on top of it... I'll think about it, but I wouldn't mind having someone else do that as well.
