Override kolla_base_distro_version

When running the kayobe-automation CI on a Zed/Antelope cloud running
Ubuntu host images, the kolla tags to
templated incorrectly. For example, a Jammy host gets
``kolla_base_distro_and_version = rocky-jammy``.

This is caused by Kayobe's ``globals.yml`` template
(``ansible/roles/kolla-ansible/templates/kolla/globals.yml``) setting
``kolla_base_distro_version`` based on Kayobe's variable of the sam
 name, which references ``os_version``. We can avoid this by explicitly
 using facts for the version in SKC's ``globals.yml`` template.
