      We should document that the PlanCache class in mongosh does not support the .list() method on 4.0 servers.

      Those who do need to access the plan cache in some form on 4.0 servers can currently do so by running the planCacheListQueryShapes command manually.

      We use $planCacheStats in the PlanCache class, which is only available in 4.2+ on the server side.

      MONGOSH-938 also has steps to reproduce.
