Decide whether auto instrumented transactions in MAUI should set Scope.Transaction

[jamescrosswell]

Description

See:

sentry-dotnet/src/Sentry.Maui.CommunityToolkit.Mvvm/MauiCommunityToolkitMvvmEventsBinder.cs

Lines 145 to 153 in 34d8490

	// Note that we may be creating a transaction here and if so we explicitly don't store it on
	// Scope.Transaction, because Scope.Transaction is AsyncLocal<T> and MAUI Apps have a global scope. The
	// results would be that we would store the transaction on the scope, but it would never be cleared again,
	// since the next call to OnPropertyChanged for this RelayCommand will (likely) be from a different thread.
	var span = hub.StartSpan(SpanName, SpanOp);
	if (span is ITransactionTracer transaction)
	{
	hub.ConfigureScope(scope => scope.Transaction = transaction);
	}

The code comment contradicts the code implementation. Either we change/remove the comment or we change the code.

If the comment is correct then the code itself needs to be changed (seems likely but need to verify).
