This will be useful in the followup commit that enables TMT test jobs on
PRs.
PRs on `main` branch should be tested with bleeding-edge dependencies
from the podman-next COPR while PRs on `release` branches should be
tested only with the official distro packages. Packit will run/skip the
relevant set of tests based on this label.
