fix: tolerate missing packages in test PyPI re-pin step

The re-pin loop iterates over all 5 PyAuto packages, but not all may
be uploaded yet due to parallel matrix runners. Add || true to prevent
failures when a package hasn't been uploaded by its matrix runner yet.

Also guard the Tests step re-pin with pip show to only re-pin packages
that are actually installed.
