Feedback: Manage databases in multiple namespaces

Page https://redis.io/docs/latest/operate/kubernetes/re-clusters/multi-namespace

There is a typo in the REAADB notice:

```
Warning:
Multi-namespace installations don't support Active-Active databases (REEADB). Only databases created with the REDB resource are supported in multi-namespace deployments at this time.
```

"REEADB" should read "**REAADB**"
