How to use UnstableResp3: true with ClusterClient

[ffly90]

I am trying to utilize the UnstableResp3 Option to do some RediSearch queries on my Redis Cluster instance. Is it possible to set the UnstableResp3: true option for the ClusterClient somehow? At The Moment I get an error like this, when running without this option:

025/02/04 13:22:10 http: panic serving [::1]:59094: RESP3 responses for this command are disabled because they may still change. Please set the flag UnstableResp3 .  See the [README](https://github.com/redis/go-redis/blob/master/README.md) and the release notes for guidance.

@ffly90 thank you for reporting. Sounds like this is missing by mistake. Let me prepare a quick PR for it.
