@Gabriel_Pu I think I found the issue. The helm chart version your are running is 8.2.4 which is Redis 6. If you downgrade to 7.6.4 it will work ootb.
Also your Redis cluster URLs are incorrect.
redis-cluster-0.redis-cluster.redis.svc.cluster.local:6379 wont resolve since there is no service with that name. You just need a single entry which in your case would be redisbit-redis-cluster.redis.svc.cluster.local:6379
