"dataVolumeCapacity" provided for kraftcontroller, but getting error "StatefulSet.apps \"kraftcontroller\" is invalid: spec.volumeClaimTemplates[0].spec.resources[storage]: Required value"

```

directly copied from example, and only added storage class.
in operator see the below error - getting error "StatefulSet.apps \"kraftcontroller\" is invalid: spec.volumeClaimTemplates[0].spec.resources[storage]: Required value".

Please advise.

Start by applying the supplied KRaftController manifest and inspecting the generated StatefulSet, focusing on how dataVolumeCapacity and storageClass are translated into volumeClaimTemplates. Compare the KRaftController example with the reported validation error; done means identifying whether the example or operator handling omits the storage quantity and recording the confirmed correction.
