Now that the infra for running dragonball tests has been enabled, let's actually make sure to have them running on each PR. The tests skipped are: * `k8s-cpu-ns.bats`, as CPU resize doesn't seem to be yet properly supported on runtime-rs * https://github.com/kata-containers/kata-containers/issues/6621 Fixes: #6605 Signed-off-by: Fabiano Fidêncio <fabiano.fidencio@intel.com>
