Trying to remove an image that is in use by containers is a confusing
experience for users who may not be aware of "external" containers which
are not displayed in
podman ps
by default (see containers/podman/issues/15006).Add some context to the error from containers/storage to guide the user
into listing external containers and force-removing the image.
