Continue 2023.2 (Bobcat) development

As a cycle-with-intermediary release with trailing deliverable type,
cinderlib's master remains the 2023.2 development branch until early
in the 2024.1 (Caracal) cycle when the cinderlib 2023.2 (Bobcat)
release is made.  So update tox.ini and .zuul.yaml to test against
cinder and os-brick stable/2023.2 instead of their master branches,
and restrict cinder and os-brick in requirements.txt to the 2023.2
series.

See the cinderlib docs for more info about this change:
https://docs.openstack.org/cinderlib/latest/contributor/contributing.html#cinderlib-tox-and-zuul-configuration-maintenance
