      Resharding fails with the error message of "The shard key provided does not have enough cardinality to make the required number of chunks of 90, it can only make 1 chunks" if the shard key doesn't have enough cardinality to make the default number of chunks which is 90 due to SERVER-92762.
      Improve this error message to include remediation.

      The shard key provided does not have enough cardinality to make the required number of chunks of 90, it can only make 1 chunks. If this is intended, reduce the numInitialChunks parameter in reshardCollection command to 1, and retry.
