[tracing] Update OpenTelemetry dependencies and fixing doc to make tracing work (#57908)

Tracing code hasn’t been maintained, and it can’t be run by relying on
the docs alone.

1.
[https://docs.ray.io/en/latest/ray-observability/user-guides/ray-tracing.html#installation](https://docs.ray.io/en/latest/ray-observability/user-guides/ray-tracing.html#installation)

`opentelemetry-api==1.1.0`
Version 1.1.0 is too old—

https://github.com/ray-project/ray/blob/b988ce4e9b0fb618b40865600c0d98f1714c3bcf/ci/docker/serve.build.Dockerfile#L47
we’re already using 1.3.0+, which is incompatible with 1.1.0.

2.
A legacy issue? This prevents the help information from being displayed.
