feat: send traffic to latest revision

If the traffic is ever sent to one of the previous revisions in the Cloud Run interface, deployment doesn't automatically send traffic to latest. This line makes sure that the traffic is sent to latest irrespective of any previous changes. Soon I'd like to make this optional.
