ci: Comply with Ansible partner certification checking [citest_skip]

https://github.com/ansible-collections/partner-certification-checker/blob/main/README.md

Unfortunately we cannot use the checkers provided by their team because they assume
the git repo is in collection format - you cannot convert to collection format first
then point the checkers at that collection.  Instead, implement our own checkers that
do the same (and more) - check with multiple versions of ansible-lint and ansible-test
to ensure we cover:

* all supported versions of EL
* Automation Hub gating
* the latest versions of Ansible, including the latest milestone version

This requires the latest version of tox-lsr
