This revert fixes my neovim treesitter issue with nix as detailed in nix-community/tree-sitter-nix#27 while following nixos-unstable.

Maybe we should have a way to disable the update script from updating certain languages until a flag is removed, or put a warning in the update instructions about which grammars to revert, since people will periodically do grammar updates.

I would like to see someone with these problems provide more context and maybe create an upstream issue.
This was not broken on Emacs, so I wonder where the problem lies.

Edit: I had this open for a while and didn't see the comments before posting.

I wonder if we shouldn't just apply nvim-treesitter/nvim-treesitter#2668 as a patch to nvim-treesitter instead as this isn't really a problem with the grammar itself.
