fix(contrib): nix flake dependencies

[lxsymington]

As mentioned in this discussion:

#27294

The Nix flake build in the contrib folder is currently failing. The discussion mentions that this is likely due to an incompatible tree-sitter version. A nix flake update resolves this issue bringing in later versions of the dependencies.

For those with nix tooling this can be verified by running:

nix run 'github:neovim/neovim?dir=contrib'

where you will get the following err:

$ nix run 'github:neovim/neovim?dir=contrib'

Whereas running:

nix run 'github:lxsymington/neovim?dir=contrib&ref=fix/contrib/nix-flake'

will enter you into a build of neovim

The plan is to remove the flake from the nix repository because of the overhead it creates to contributors and move it to https://github.com/nix-community/neovim-nightly-overlay/. I haven't had the time to do so. Is this something you would be interested in ?

[lxsymington]

I'm pretty new to Nix so this would likely take me a bit of time. I'm interested in having a go if that's agreeable though?

[justinmk]

Meanwhile should we merge this or not @teto ?

[justinmk]

merged #28394

but waiting for this to be moved to https://github.com/nix-community/neovim-nightly-overlay/ as discussed

[teto]

I was on holiday sry. I will try to merge @ribru17 's flake in the nix-community overlay and once it's done I can do the announcement remove it from repo.
