The instrumentation test issues can migrate to the contrib repo as part of open-telemetry/opentelemetry-dotnet#5526.

@reyang - This is tracked with #1724. I think we should close this one as the failures are not just confined to OpenTelemetry.Instrumentation.AspNetCore.Tests.BasicTests.AddAspNetCoreInstrumentation_BadArgs

Closing. I have didn't see any issues after migration to contrib repository.
