chore(deps): update opentelemetry

[rami3l]

Supersedes #4182.

Following #4182 (comment), I realized that since otel is not an essential part of our project (it's used in benchmarks for the timeline view only), the following change has brought us no benefits:

opentelemetry::global::shutdown_tracer_provider() is removed.
Now, you should explicitly call shutdown() on the created tracer provider.
[..]
This now makes shutdown consistent across signals.

... so it'd be nice to just stick to the original behavior of shutdown_tracer_provider(), which is simply replacing the global tracer provider with NoopTracerProvider::new() and dropping the replaced provider immediately:

pub fn set_tracer_provider<P, T, S>(new_provider: P) -> GlobalTracerProvider
where
    S: trace::Span + Send + Sync + 'static,
    T: trace::Tracer<Span = S> + Send + Sync + 'static,
    P: trace::TracerProvider<Tracer = T> + Send + Sync + 'static,
{
    let mut tracer_provider = GLOBAL_TRACER_PROVIDER
        .write()
        .expect("GLOBAL_TRACER_PROVIDER RwLock poisoned");
    mem::replace(
        &mut *tracer_provider,
        GlobalTracerProvider::new(new_provider),
    )
}

pub fn shutdown_tracer_provider() {
    let mut tracer_provider = GLOBAL_TRACER_PROVIDER
        .write()
        .expect("GLOBAL_TRACER_PROVIDER RwLock poisoned");
    let _ = mem::replace(
        &mut *tracer_provider,
        GlobalTracerProvider::new(NoopTracerProvider::new()),
    );
}

Regarding the setup/shutdown ergonomics, I've made a simple guard to bring back (before|after)_test_async() with minimal efforts, so this has also addressed the test-related part of #4195, although it'd probably still be nice to be able to fetch e.g. logger filter levels directly from within Process, so the remainder of that issue stays valid.

Good stuff!
