Description

SERVER-55313 demonstrates some confusion over a downgrade floor from MongoDB 4.2.6+ to any earlier version.

I'd like to request two changes:

1) Here, include with existing downgrade floor guidance daniel.gottlieb's guidance in SERVER-55313 about how to downgrade from 4.2.6+ to an earlier version.

2) Duplicate the same content about downgrading (including the above change) in the Downgrade 4.2 to 4.0 documentation
