prow-scheduler: Enable scheduling

[danilo-gemoli]

ProwJob CRD has been updated #49766 and the scheduler is actually running #49859.
This PR enables a PJ to be created in state: scheduling by the components cited in these PRs:

• scheduler: handle scheduling everywhere kubernetes/test-infra#32173
• scheduler: opt-in prow scheduling everywhere ci-tools#4044

The current scheduling strategy is failover with no mappings (see here), so this means the scheduler will simply update .status.state of each PJ, leaving .spec.cluster untouched.

The following is an example of how the reconciler would patch a PJ:

apiVersion: prow.k8s.io/v1
kind: ProwJob
spec:
  cluster: build05
status:
- state: scheduling
+ state: triggered
