Requesting more deployments does not start a new GCP build

[armenzg]

I deployed a change and I tried to deploy it few times since the output showed to me an intermittent issue. The right solution was to re-run the GCP build and then request a new Freight deployment.

IMHO I believe we should either encourage the user to re-run their build first OR make new Freight deployments trigger new GCP builds.

I checked sentry and getsentry commits to see anything in the CI failing, however, it was successful on both repos.
