fix: update the snapshotschedule post adding default reclaim policy

[strivedi-px]

What type of PR is this?

failing test

What this PR does / why we need it In the startVolumeSnapshot function, we were fetching the latest copy of the snapshotschedule from the CR however in the handle() function which actually calls the startVolumeSnapshot() function, we were not persisting the updated default reclaimPolicy to Delete in the CR. Due to this, the ownerReference wasn't getting added to the volumeSnapshot resource. This PR adds the change to persist the changed default reclaimPolicy to the CR as soon as it's updated in the object.

Does this PR change a user-facing CRD or CLI?: No

Is a release note needed?: No

Does this change need to be cherry-picked to a release branch?: Yes, release-24.2.0 branch.
