Describe the bug

I tried using code like this:

batch_operations = [
("upsert", tuple([session_item] + message_pair_items))
]
await container.execute_item_batch(batch_operations=batch_operations, partition_key=[entra_oid, session_id])

That results in an error in the SDK however ("operation" is undefined), arising from this code lacking "upsert"--

        elif len(args) == 2:
            if operation_type.lower() == "replace":
                operation = {"operationType": "Replace",
                             "id": args[0],
                             "resourceBody": args[1]}
            elif operation_type.lower() == "patch":
                operation = {"operationType": "Patch",
                             "id": args[0],
                             "resourceBody": {"operations": args[1]}}
                filter_predicate = kwargs.pop("filter_predicate", None)
                if filter_predicate is not None:
                    operation["resourceBody"]["condition"] = filter_predicate

Mark says that the .NET SDK has equivalent functionality for upsert and delete. And if for some reason they dont work, the error should be better.
