Hi, just realized that the oteltest is removed in the latest versions.

We had tests like oteltest.NewTracerProvider(oteltest.WithSpanRecorder) and oteltest.SpanRecorder in our code before, what's the recommended substitution after the removal?

@gigglegrig Please take a look at the sdk/trace/tracetest package, specifically "go.opentelemetry.io/otel/skd/trace/tracetest".SpanRecorder which can be registered with the default SDK TracerProvider.
