Validation steps

• Ensure all container images have repository and tag on the same level to ensure that all container images are included in rancher-images.txt which are used by airgap customers.

  Ex:-
    longhorn-controller:
      repository: rancher/hardened-sriov-cni
      tag: v2.6.3-build20230913

What is wrong about this RC?
I would be tempted to remove rc.1, or even both RCs now that v0.13.4 has been released, but not sure I understand why rc.2 in particular would need to be removed 🤔
