ci: wait for deployment rollout in k8s-deployment (#3947)

Previously, it could happen that `web` didn't have its deployment fully
complete, which used to make `port-forward` fail quite consistently.

By leveraging `rollout status` we can wait for the underlying pods to
get to a `READY` state (instead of plain `RUN`) before moving forward.
