fix docs.hacc.space

this is a slightly cursed work around; see the comment.

Alternatively, we could pass in the $src attribute of that derivation
via callPackage (passing it through all the way from flake.nix), but tbh
that sounds like too much effort rn.

Have fun with confusingly long paths in the nix store 🙃
