[Website]: Documentation does not mention data stream rollover and deletion behavior

### Before you submit

- [x] This issue is about a documentation page, flow, or piece of content.

### Type of issue

Missing information

### What documentation page or section is affected

https://www.elastic.co/docs/deploy-manage/tools/cross-cluster-replication/manage-auto-follow-patterns

### What happened?

It seems that rolled over indices that are deleted on primary cluster due to lifecycle policy are deleted also on the follower cluster.

This is expected and logical behavior.

However, it is not mentioned on linked page, nor I could it find anywhere else really. It would be great to explicitly document behavior around deletion of data stream indices with regards to CCR.

Especially because for non-data stream indices, it looks like deletions are not propagated to the follower cluster.
