Wait for CI/CD success before deploying

### What problem are you trying to solve?

If CI/CD (GitHub Actions workflows) has failed for the branch, Deno Deploy will still deploy the new changes.

### Describe the solution you'd like

Wait for CI/CD to pass before deploying.

### Describe alternatives you've considered

Deploying using CI/CD, but this feature doesn't seem to be available on the new version of Deno Deploy.

### Documentation, Adoption, Migration Strategy

There should be an option somewhere to wait for CI/CD to pass.

Start by reviewing the GitHub Actions workflows and the Deno Deploy deployment configuration to determine where failed CI currently allows deployment. Done means an available option prevents deployment until the relevant CI/CD workflow succeeds.
