def self.version

If redis-client and redis > 5 are installed, than they will be in sync, and only redis-client will be installed.
For example, if Sidekiq 7 and Redis 4 are installed: both redis and redis-client will be installed.
Because Redis 4 does not depend on redis-client, it's possible for both gems to be installed at the same time.
Since Redis 5, instrumentation happens in a separate gem: redis-client.
Until Redis 4, all instrumentation happened in one gem: redis.
