python: Avoid relying on Collection supertype of QuerySet.

QuerySet doesn’t implement __contains__, so it can’t be a subtype of
Container or Collection (https://code.djangoproject.com/ticket/35154).
This incorrect subtyping annotation was removed in
https://github.com/typeddjango/django-stubs/pull/1925, so we need to
stop relying on it before upgrading to django-stubs 5.
