related to https://issues.redhat.com/browse/ACM-11817

Since Velero CRDs are no longer installed by ACM , we should allow the user to install a version different than the one used by the backup chart, on an STS cluster or when using this annotation https://github.com/stolostron/multiclusterhub-operator/tree/main?tab=readme-ov-file#overriding-oadp-operator-subscription

We should allow installing an OADP version newer ( not older ) than the one installed by the chart

So only this should be validated ( 3 templates ):

1. There is an OADP installed under the backup ns
2. The OADP version installed under the backup ns should be the same as the chart or a newer version
3. Any OADP installed outside of the backup ns should match the version of the OADP installed under the backup ns
