Thanks for wanting to report an issue you've found in redis-py. Please delete this text and fill in the template below.
It is of course not always possible to reduce your code to a small test case, but it's highly appreciated to have as much data as possible. Thank you!

Version: What redis-py and what redis version is the issue happening on?

Docs

Description: Description of your issue, stack traces from errors and code that reproduces the issue

The documentation for the timeseries module commands seems to be incorrect. If one tries to follow the example:

import redis
r = redis.Redis()
r.timeseries().create(2, retension_msecs=5)

An AttributeError is thrown saying redis does not have attribute timeseries.

After looking at the source and testing a bit, it seems the below is the right way to do it

import redis
r = redis.Redis()
r.ts().create(2, retension_msecs=5)

The docs should likely be updated if this is correct. Thanks!
