Bug: Parent span duration is not correctly calculated

[ikovac]

As you can see on the screenshot below, the parent span duration is not calculated correctly.
Parent span (provider->identityservice.get) should also include the duration of child spans in its own duration. The same goes for controller->identitycontroller.profile.
I am using nestjs version 9 and zipkin in order to visualize traces.

I think the issue is in this line: https://github.com/MetinSeylan/Nestjs-OpenTelemetry/blob/main/src/Trace/Injectors/BaseTraceInjector.ts#L68C13-L68C13
because this issue occurs with async functions. There should be other check to determine if the function is async.
