The collection bulk write type in the C++ Driver is mongocxx::bulk_write, while the client bulk write type is mongocxx::client_bulk_write. For clarity, bulk_write should be aliased as collection_bulk_write. This would align with CDRIVER-6347, which proposes introducing similar typedefs in the C Driver.

If possible, we may also want to consider deprecating the name bulk_write to encourage the use of the new name.
