ci: bump ansible-lint to v25; provide collection requirements for ans…

…ible-lint

There is a new version of ansible-lint - v25.
Newer versions of ansible-lint require the collection requirements to be
installed so it can find the modules/plugins.
Enhance our ansible-lint ci job to provide the collection requirements,
including merging the runtime meta/collection-requirements.yml with
the testing tests/collection-requirements.yml.
This should somewhat mitigate the loss of ansible-plugin-scan.
We have to remove mock_modules that are actually present now.
