Describe the feature you'd like

Support for the latest official Go Redis client module (github.com/redis/go-redis/v9) in the dd-trace-go package.

Is your feature request related to a problem?

Currently, dd-trace-go only supports tracing instrumentation for earlier versions of the Go Redis client (github.com/go-redis/redis/v8). With the recent migration of the Redis client to the official Redis GitHub organization (github.com/redis/go-redis/v9), users upgrading to this actively maintained and officially recommended module cannot easily leverage Datadog's tracing features.

This gap prevents comprehensive monitoring and observability for applications using the most up-to-date Redis client version, limiting visibility into Redis operations.

Describe alternatives you've considered

Currently, as an alternative, developers either:

• Delay upgrading to github.com/redis/go-redis/v9.
• Manually implement tracing spans around Redis commands, which is inefficient and error-prone.

Additional context

• Official Redis client migration announcement: Redis.io Blog
• Go Redis v9 documentation: pkg.go.dev

👋 @galHalup

redis/go-redis/v9 is officially supported: https://github.com/DataDog/dd-trace-go/tree/main/contrib/redis/go-redis.v9

It is in a different folder (under redis/go-redis instead of go-redis/redis) to mirror the package name (earlier versions were different, e.g. github.com/go-redis/redis/v8).
