Allow to use redis>=5

[Taragolis]

Originally redis-py limited to <5 by the problem in Celery celery/celery#8442 and Kombu celery/kombu#1776

Seems like the limitation is gone into the latest version of celery:

• support redis 5.x celery/celery#8504
• redis>=4.5.2,<5.0.2,!=4.5.5 -> redis>=4.5.2,!=5.0.2,!=4.5.5 celery/kombu#1969

Also add "redis" extras into the Celery provider, so it might limited independently of Redis Provider
