Add zig tree-sitter support

[voroskoi]

Highlighting works, indenting not so much, but I guess it is more than nothing.

indents.scm and folds.scm are not supported. For indents you'll have to define a indents.toml instead, which looks like this: https://github.com/helix-editor/helix/blob/master/runtime/queries/rust/indents.toml

Thank You for the heads up, I have cleaned up things a bit. I have switched to a different grammar repo, but nvim-treesitter also use this one, so it is probably more up to date. Still have to figure out the indenting, does not work for me.

You're getting there!

Ok, I think the highlights part is fine for initial support. Time to figure out the indenting part.

I have removed the indents.toml as I can not figure out why it does not do anything.

It seems like the highlighting is a little incorrect:

Function calls are being highlighted as variables. It should be ready to merge after that gets corrected. You can also leave (IDENTIFIER) @variable at the end of the highlights.scm so everything else gets highlighted as variables.

Can you show me the file (it's gone from git history)? I might be able to help there.

Nice work! I'll do some testing on indents but I think it's good for merge 👍
