When enabling some tests that were previously commented out with a TODO SERVER-98461 comment above them, I found that some commands update / bulkWrite do not return the writeConcernError s as expected by the test.

These test errors are not related to findAndModify (and thus SERVER-98461), so we did not enable the failing assertions as part of SERVER-98461. But we should definitely follow this up and make sure that update / bulkWrite always return writeConcernError s as expected.
