Drop py3.10 from Tempest

Due to constraints update(rpds-py) in requirements, Tempest master stopped working on
python 3.10, which blocks the tempest master gate as well as the stable/2025.1 Ubuntu
Jammy jobs.

- https://review.opendev.org/c/openstack/requirements/+/990790

As python 3.10 is not in current cycle (2026.2) testing runtime, we need to drop its
support from tempest master and use the compatible tempest tag for python 3.10 testing.

Tempest drops python3.10 support and pythin 3.10 jobs (ubuntu jammy jobs) can use the
46.3.0 tag to test it.
