Next step: Release a bounded version of the gem to not install the instrumentation on Redis 5 as a bugfix bump
After: Add support for Redis 5

[kaylareopelle]

Here's the main PR that introduced Redis 5.x support in the New Relic Ruby agent: newrelic/newrelic-ruby-agent#1611

[kaylareopelle]

It looks like some work has already taken place to support Redis 5: #121

I don't think the OpenTelemetry::Instrumentation::Redis::Patches::RedisV4Client tests should be running on a Redis 5.x appraisal. However, the two failures from OpenTelemetry::Instrumentation::Redis::Middlewares::RedisClientInstrumentation should be passing.
