Improve commit message for containers release

[rndstr]

Currently

Release containers

default:deployment/foo
- quay.io/bar/foo:master-d9500ad8

default:deployment/moo
- quay.io/bar/moo:master-d9500ad8

A better version

Release containers to default:deployment/foo, default:deployment/moo

default:deployment/foo
- quay.io/bar/foo:master-d9500ad8

default:deployment/moo
- quay.io/bar/moo:master-d9500ad8

which brings it more in tune with other commit messages that mention the workloads in the main message.

I did talk with @lelenanam about this which she intended to do as part of the events/notification work
