fix(grfn/xanthous): Update shell for new depot structure r/2652

Since 473604f5675c455a65b91e287b125a9e042ae39f (CL/2910), depot hasn't
been directly exposing `pkgs` as an attribute, instead exposing it via
third_party.nixpkgs - the xanthous shell.nix isn't checked in CI, so it
was missed as part of that refactor - this updates it to be in line with
that
