WIP: Test GHCR mirror pre-pull for dockcross images

Temporarily point python-build-workflow at the
ghcr-mirror-dockcross-images branch of
ITKRemoteModuleBuildTestPackageAction to test the
pre-pull step with GHCR fallback logic.

Pin to ITK v5.4.5 wheel/package tags to match the
v5.4.5 build cache.
