Update OpenTelemetry Tracing version status

[hanyuancheung]

Follow: #12929
Fixs: #12460
Noticed that OpenTelemetry has released some stable versions as well as new features. Now update its version, and remove the experimental status in tracing config.

Overall Looks good to me, please add an entry into 3.6 CHANGELOG.

We also need an agreement as discussed in issues/13775.

[serathius]

Before marking distributed tracing as a stable feature we need to agree on expectations of how stable tracing for etcd should look like. Does it work? Do we have enough tests? Is tracking used withing Etcd codebase?

Would be good to discuss it with the K8s tracing owner @dashpole

[dashpole]

An integration test similar to kubernetes/kubernetes#103234 would be useful. @hanyuancheung have you gotten any user feedback from trying to use the feature, or know of successful use anywhere?

Thanks for the info. etcd needs to add similar integration test. Just raised an issue to track this.

I agree. This PR should focus on updating otel tracing version to the newest one, and I've noticed @ahrtr has opened the issue to track the addition integration test for etcd tracing.

I'll also work on #13814 after this one finished, to make sure the feature is useful with the integration test 😄 Thx for ur suggestion!

[serathius]

Let's have a separate PR to stabilize distributing tracing feature. We still have some work before stabilization.

[hanyuancheung]

I get it. So this PR should just work on updating the version of OpenTelemetry right?
If so, I'll cancel the changes of all stabilization work ~

[serathius]

Yes, we can update OpenTelemetry now and decide separably to stabilize the tracing.

The google.golang.org/grpc was already bumped to 1.47 in 14125, but the go.opentelemetry.io/otel wasn't bumped in that PR.

Could you rebase this PR and bump the go.opentelemetry.io/otel?

In this commit 88cd0fe, otel is already the latest version

Thanks @houseme for the confirmation.
