Resolves https://github.com/ansible/ansible/issues/75320
The option `--prime-containers` was chosen over `--docker-pull-only` to match the recently added `--prime-venvs` option for sanity tests.
It would also fit well with a future `--prime-requirements` option for pre-installing requirements for unit and integration tests.
