fix: disable doc generation for OpenStack clients (cliff sphinxext Python 3.14)

cliff's sphinxext uses argparse._format_actions_usage() which was
removed in Python 3.14. Disable doc generation via spec overlay
(%global with_doc 0) for python-heatclient, python-manilaclient,
python-octaviaclient, and python-openstackclient until the upstream
cliff fix (openstack/cliff@391261c) is released.

Also add python-oslo-config to check-skip-initial-failures.

Add ^ and $ anchors to prevent unintended substring matches on
commented lines or other macro uses. Consistent with the pattern
used in python-stestr.comp.toml.
