Fix infinite loop in seed container deployment

The deploy.yml playbook previously called deploy-container.yml, but this
was changed to call itself when podman support was added [1]. It would
then recursively loop until failure. This change reverts that, so
deploy-container.yml is called instead.

Add a test to seed jobs, to catch any regression in CI.
