Nix flake build currently failing

[mrjones2014]

Building with the Nix flake is currently failing, and I'm not sure why. Here's the log output:

You need to update tree-sitter to the version specified in our cmake build scripts.

[mrjones2014]

Sorry, I'm still relatively new to Nix. Wouldn't those versions be specified by Neovim's flake.nix itself?

[clason]

I wouldn't know; the Nix flake is community contributed and not maintained by us (that's why it's in contrib/).

[lxsymington]

A nix flake update in the contrib directory appears to fix the build issue for me.

What would be needed to PR this?
