When executing explain on aggregate it generates an error with WriteConcern

      Problem Statement/Rationale

      When I execute an explain with executionStats from mongosh I get an error instead of the real result, the error makes no sense:
      MongoInvalidArgumentError: Option "explain" cannot be used on an aggregate call with writeConcern
      If I execte the same command from legacy mongo shell it works as expected.

      Steps to Reproduce

      Execute the following on Atlas from mongosh:
      tlas atlas-diu7sz-shard-0 [primary] anydb> db.anycollection.explain("executionStats").aggregate([\{ "$match": {} }])
      MongoInvalidArgumentError: Option "explain" cannot be used on an aggregate call with writeConcern
      Reproduced with version 1.0.7

      Expected Results

      Get the explain plan as it happens with legacy mongo shell.
