Previously, the `service.name` attribute got overridden with "unknown service" from the detector used in `Resource::default`. To avoid this, we are now manually composing the two other detectors. This gives us a useful set of default labels from within the code yet it allows overriding all of them using `OTEL_RESOURCE_ATTRIBUTES`.
