Quarantine qa/qa/specs/features/browser_ui/5_package/package_registry/pypi_repository_spec.rb

This specs fails because of a dependency upgrade gitlab-org/quality/engineering-productivity/master-broken-incidents#7046 (closed).

It seems to be resolved because twine was yanked in https://pypi.org/project/twine/5.1.0/ but we can’t test this without a long-term quarantine.
