Reason for revert:

Needed-By: https://review.opendev.org/c/openstack/openstack-zuul-jobs/+/882175

TC has been discussing about re-adding the python 3.8
testing in current master 2023.2 release testing.

- https://lists.openstack.org/pipermail/openstack-discuss/2023-April/033469.html

While governance changes are under review, TC agreed to add py3.8 testing
so that we do not see more project/lib dropping python 3.8 and make them
uninstalable on python 3.8
