[UI] Notifications for Backup are Labeled as Bucket.

### problem

For some reason, while I was doing Backup operations, the UI was telling me Bucket.

I hope it is just a labeling issue and not a logic issue.

ACS 4.22.0.1

### What to do about it?

_No response_

Reproduce the backup operation in ACS 4.22.0.1 and compare the UI label shown in the attached screenshot with the operation being performed. Confirm that the notification says “Backup” rather than “Bucket,” and verify that the underlying operation is unaffected.
