Detailed steps to reproduce the problem?

c = MongoClient()
c.admin.command({"bulkWrite": 1, "nsInfo": "test.test", "ops": []})

https://github.com/mongodb/mongo-python-driver/blob/c9a85ad321f98caf314fc9da7a367e94d661abac/pymongo/message.py#L411 here we use a map to find the "docs" for the command

https://github.com/mongodb/mongo-python-driver/blob/c9a85ad321f98caf314fc9da7a367e94d661abac/pymongo/message.py#L108 this map says its bulkWrite which might be for some internal way of representing legacy bulkWrite commands cause I think the value in this map needs to be ops

Definition of done: what must be done to consider the task complete?

you should be able to manually run a multi namespace bulkWrite without using the helper. command() should handle any valid command. for now I'm just going to use the helper
