buildPebbleApp broken since 7aca2ec: packages.pebble-tool -> pkgs.pebble-tool?

[t184256]

buildPebbleApp fails when used from an external flake input since 7aca2ec:

error: attribute 'pebble-tool' missing
at /nix/store/f4xhs6haf7j8rgfbz639h6cj9mbklkjw-source/flake.nix:51:25:
50|           inherit pkgs nixpkgs system;
51|           pebble-tool = packages.pebble-tool;
  |                         ^
52|           python-libs = pkgs.callPackage ./derivations/pebble-tool/python-libs.nix { };

Should probably be just pkgs.pebble-tool from the overlay?

Tested using no-time-for-this as an example of a project using buildPebbleApp that used to work before.
