Documentation Request Summary:

MongoDB documentation should be updated to indicate the deprecation of the storage Engine MMAPv1. A docs ticket is already in place for that and linked to the Epic : https://jira.mongodb.org/browse/DOCS-10986

Engineering Ticket Description:

The MMAPv1 storage engine is becoming increasingly outdated in terms of feature support, and the legacy code is becoming more expensive to maintain - we should deprecate MMAPv1, since WiredTiger is now the preferred storage engine.
