Description

Downstream Change Summary

Flagging Docs on this change as our previous patch for supporting mapReduce via db.collection.explain() erroneously took a command object rather than the same arguments as db.collection.mapReduce(). This patch corrects this.

Description of Linked Ticket

This fails with FailedToParse, "explain command requires a nested object"

per comments in DOCS-13565, noted the `verbose` `mapReduce` option is ignored starting in v4.4.
