feat: Upgrade Redis 3 to 4 (#8293)

BREAKING CHANGE: This release upgrades to Redis 4; if you are using the Redis cache adapter with Parse Server then this is a breaking change as the Redis client options have changed; see the [Redis migration guide](https://github.com/redis/node-redis/blob/redis%404.0.0/docs/v3-to-v4.md) for more details (#8293)
