Add a test for verifying OCP versions supported in a release

OCP versions on which a release will be shipped on is included in the operator bundle Dockerfile.in via the label

LABEL com.redhat.openshift.versions="v4.11-v4.13"

https://gitlab.cee.redhat.com/tekton/p12n/-/blob/pipelines-1.11-rhel-8/distgit/containers/openshift-pipelines-operator-bundle/Dockerfile.in

Also, the `maxOpenShiftVersion` field mentioned here

properties:
  - type: olm.maxOpenShiftVersion
    value: "4.13"

https://gitlab.cee.redhat.com/tekton/p12n/-/blob/pipelines-1.11-rhel-8/distgit/containers/openshift-pipelines-operator-bundle/metadata/properties.yaml

Acceptance criteria:

• This is easy to misconfigure and we need a test to make sure this is correctly set.
• Also, this information needs to be directly read from this file and reflected in the dashboard as well.
