11586: ci: Fix extraneous alpha draft releases r=AaronFriel a=AaronFriel

The [PR workflow to update Pulumi YAML to 1.0.4](https://github.com/pulumi/pulumi/actions/runs/3642973677) shows that it created a draft release, and this has been the case for all contributors' PRs.

This fixes the extra alpha releases created as a result of pull requests. The job "prepare-release" shouldn't run unless the ci/test label is set, indicating an intent to evaluate the full CI pipeline.
