Subject: [PATCH] nix: update zigCacheHash, mention that building pkg requires
 src

This updates the zigCacheHash and just adds a note mentioning that using
the package will require you to rebuild LLVM 17 and Zig, and directs
people to use the devShell until this is resolved.

This is likely good advice for most people until such time that both are
in nixpkgs (or at least LLVM 17 as it's by far the bigger culprit here).
