Chris Marchesi c3b44020f4 nix: add GitHub Actions workflow ...

This adds a nix workflow that does the following:

* Checks to see if the Zig cache fixed derivation needs its hash
  updated. It does this by downloading a new cache, calculating the
  hash, and comparing it against what has already been set. If the hash
  is different, the workflow fails.
* Runs a Nix build if the hash is OK, testing the build of
  packages.ghostty (using "nix build .")

The cache workflow we use in the build job comes from:
  https://github.com/DeterminateSystems/magic-nix-cache-action/

Fixes #937.
