[Docs]: Misleading documentation regarding Azure Storage #5974

Is there an existing issue already for your request/idea?

• I have searched for an existing issue, and could not find anything. I believe this is a new documentation enhancement to be evaluated.

What problem in the existing documentation this issue aims to solve?

Storage documentation mentioned that Azure support pvc expending only on specific region.

https://github.com/cloudnative-pg/cloudnative-pg/blob/main/docs/src/storage.md#expanding-pvc-volumes-on-aks

That seem not more the case
https://learn.microsoft.com/en-us/azure/aks/azure-disk-csi#resize-a-persistent-volume-without-downtime

Pheraps the option ENABLE_AZURE_PVC_UPDATES can be deprecated or remove to simply the code ?
