Patch attached with documentation changes but {{CdcrReplicationHandlerTest}} is failing due to changed behavior of disabling Buffer permanently.
7 tests failed.

Looking into studying and implement what should be intended behavior now.

> 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
