Currently the ci-on-push workflow that runs on PRs runs
two jobs: gatekeeper-skipper.yaml and ci.yaml. In order
to test things like for the error

```
on topic branches, we need ci-devel.yaml to have an
extra workflow to match ci-on-push, so add the build-checks
as this is helpful to run on topic branches anyway.
