OpenTelemetry

Hello!
Would you have any examples of how to implement OpenTelemetry in go-chi?

I even managed to implement it, but it just does the tracing. In my case, I communicate with redis and this metric does not appear, even using redis otel.

The issue names no repository files, tests, or existing entry points; start by locating go-chi's middleware documentation and examples. Determine what an OpenTelemetry example should cover for HTTP tracing and Redis metrics, then document a reproducible setup whose tracing and Redis metrics are both visible.
