Subject: [PATCH] feat(lang): add nix language support (#2956)

In the future we can add:
- dap / debugger support, if this is ever possible or needed.
- extend neotest, if this is ever needed, for most people I suspect not
needed.
- linting, if this is ever needed.
- ~~maybe enhance nvim-cmp behavior with nixpkgs, rust lang extension
crates.nvim does smt with nvim-cmp, other language extensions don't.~~

I think its already good to merge this PR, we can add these enhancements
later, if they are ever needed.
