This PR builds the foundation for us to start migrating the
cri-containerd tests from Jenkins to GitHub Actions.
Right now the test does nothing and should always finish successfully.
The coming PRs will actually introduce logic to the `gha-run.sh` script
where we'll be able to run the tests and make sure those pass before
having them actually merged.
Fixes: #6543
