Misleading info on managedLifecycle SGBackups property

Summary

I think the description for the spec.managedLifecycle property on SGBackups is misleading.

The description says:

Indicate if this backup is permanent and should not be removed by the automated retention policy. Default is false.

This is wrong, since it actually works the opposite way. If managedLifecycle == true, then backup is not permanent and will in fact be removed by the automated retention policy.

Possible Solution

Rewrite description/tooltip as:

Indicate if this backup is not permanent and should be removed by the automated retention policy. Default is false.```

### Environment

- StackGres version: `1.7`
