Investigate changes in SERVER-53247: Disable enableMajorityReadConcern:false

Description

Description of Linked Ticket

WiredTiger recently completed an investigation of the feasibility of removing enableMajorityReadConcern:false now that WT has durable history. After reviewing the findings of that investigation, we are moving forward with Removing Support for enableMajorityReadConcern:false. Durable History addresses cache pressure concerns around majority commit point lag allowing for the removal of eMRC:false (a mode of operation that does not allow distributed transactions and other features).

We need to disable support for eMRC:false as a first step.

In a future release, we will fully remove support for eMRC:false.

Scope of changes

Review https://docs.mongodb.com/manual/reference/read-concern-majority/#disable-read-concern-majority and possibly other mentions?

One approach might be to replace that section with a blurb like 'Starting in MDB 5.0, you can't do this. If you're an older version, refer to those docs to see how to disable maj RC."
