--------------------------------------
Thanks Amrit! I've gone and made some more changes to remove the concept of buffering from our docs. precommit is also happy.
I'd like you to review the final patch and then I'll go ahead and commit it.

> Today, if we see the current CDCR documentation page, buffering is "disabled" by default in both source and target. We don't see any purpose served by Cdcr buffering and it is quite an overhead considering it can take a lot heap space (tlogs ptr) and forever retention of tlogs on the disk when enabled. Also today, even if we disable buffer from API on source , considering it was enabled at startup, tlogs are never purged on leader node of shards of source, refer jira: SOLR-11652
