Add support for Node-Redis 4

[qerub]

The NodeJS layer currently uses @opentelemetry/instrumentation-redis that only supports Node-Redis 2 and 3.^0

Please consider adding @opentelemetry/instrumentation-redis-4^2 to the set of available instrumentations.

Based on what @opentelemetry/auto-instrumentations-node^3 does I believe it's fine to provide both at the same time.^4
