Add support for python redis package for version 5.0.0

[nivsk98]

Is your feature request related to a problem? Please describe.
I'm trying to use async redis with cluster (redis.asyncio.cluster) which is only supported on versions 5+ and at the same time I want to use pottery redlock but pottery only supports versions between 4-5 no included 5

Describe the solution you'd like
Pottery to support python redis package with version 5.0.0 (5+ is optional)

Describe alternatives you've considered
Copy the redlock code in pottery and use it in my code without the need for the pottery package.
