Review use of BC41004 warning

[RussKie]

The latest changes from dotnet/runtime (#3804) couldn't be merged due to build failures:

##[error]src\Microsoft.VisualBasic.Forms\src\Microsoft\VisualBasic\Devices\Network.vb(822,20): error BC41004: (NETCORE_ENGINEERING_TELEMETRY=Build) First statement of this 'Sub New' should be an explicit call to 'MyBase.New' or 'MyClass.New' because the 'Public Overloads Sub New()' in the base class 'WebClient' of 'WebClientExtended' is marked obsolete: 'Use HttpClient instead.'

The error was suppressed in 590399f.

The suppression needs to be reviewed, and corrected.

@KlausLoeffelmann can you please validate that we don't need to do anything here?

Actually, we might need to do something here. I'll talk to @KathleenDollard when I am back in September, to discuss how we tackle this and the fact, that we also have problems still with ensuring Single-Instance in an RDP environment. This might be related, and we may need a different approach altogether.

This gets mitigated when we finish this #9807, which we cannot do in .NET 8.
