The latest conda package (2.3.0) does not pin to pymongo<4.0

[ShaneHarvey]

I had the following issue reported to motor today: MOTOR-862

Today, when I installed motor 2.3.0 with the command:

conda install motor

It also installed pymongo 4.0 that is incompatible with motor.
It crashed with the following error:

Traceback (most recent call last):
...
File "/opt/conda/envs/doogle_server/lib/python3.9/site-packages/motor/__init__.py", line 35, in <module>
from .motor_tornado import *
File "/opt/conda/envs/doogle_server/lib/python3.9/site-packages/motor/motor_tornado.py", line 17, in <module>
from . import core, motor_gridfs
File "/opt/conda/envs/doogle_server/lib/python3.9/site-packages/motor/core.py", line 27, in <module>
import pymongo.mongo_replica_set_client
ModuleNotFoundError: No module named 'pymongo.mongo_replica_set_client'

I solve it (as a workaround) by using the pipy package (2.5.0) that pinned the pymongo version

pip install motor

I am not sure why it automatically pulls in PyMongo 4.0 because the motor 2.3.0 release correctly pins to pymongo >=3.11,<4: https://github.com/mongodb/motor/blob/2.3.0/setup.py#L32. Does conda install not respect version requirements in dependencies?
