feat(pypi): Add extra_hub_aliases to pip_repository too (#2426)

The extra_hub_aliases feature from #2369 has bindings in the pip
extension
for bzlmod users, but not pip_repository for WORKSPACE users.  But it
_can_ work for either, so this patch moves it to the list of attrs the
two share and makes it work with the latter.
