Add the pod name when we use podman ps -p

The pod name does not appear when doing `podman ps -p`.
It is missing as the documentation says:
-p, --pod              Print the ID and name of the pod the containers are associated with

The pod name is added in the ps output and checked in unit tests.

Closes #4703
