Description of problem:
"ReadOnlyMany" should not added to supported values in memory dump

Version-Release number of selected component (if applicable):
CNV-v4.12.0-450
Client Version: version.Info

{GitVersion:"v0.56.0-rc.0", GitCommit:"7ae67511af8d24e85c1668e6321db08981215e7d", GitTreeState:"clean", BuildDate:"2022-08-01T13:37:38Z", GoVersion:"go1.17.8", Compiler:"gc", Platform:"linux/amd64"}

How reproducible:
Always

Steps to Reproduce:
1. Create a VM
2. Do memory dump with an unsupported access mode, got only warning - supported values: "ReadOnlyMany", "ReadWriteMany", "ReadWriteOnce"
3. Do memory dump with access mode "ReadOnlyMany", got warning - cannot dump memory to a readonly pvc

Actual results:
$ virtctl memory-dump get vm-fedora-datavolume --claim-name=memoryvolume --create-claim --access-mode=RWX
PersistentVolumeClaim "memoryvolume" is invalid: spec.accessModes: Unsupported value: "RWX": supported values: "ReadOnlyMany", "ReadWriteMany", "ReadWriteOnce"

$ virtctl memory-dump get vm-fedora-datavolume --claim-name=memoryvolume --create-claim --access-mode=ReadOnlyMany
cannot dump memory to a readonly pvc, use either ReadWriteOnce or ReadWriteMany if supported

Expected results:
"ReadOnlyMany" should not added to supported values in memory dump
