Numerous CS9270 warnings caused by generated code

[dotMorten]

Description

When I build my project, I get numerous warnings from the generated code like this:

warning CS9270: 'InterceptsLocationAttribute(string, int, int)' is not supported. Move to 'InterceptableLocation'-based generation of these attributes instead. (dotnet/roslyn#72133)

Steps to Reproduce

1. Clone the repro https://github.com/Esri/arcgis-toolkit-dotnet at tag v200.8.0 git clone https://github.com/Esri/arcgis-toolkit-dotnet --tag 200.8.0
2. Open solution \src\Esri.ArcGISRuntime.Toolkit.sln in Visual Studio and build the project Esri.ArcGISRuntime.Toolkit.Maui
3. Observe all the build warnings

Note that the project targets .NET 9, but same issue happens if you upgrade the targets to .NET 10.

Did you find any workaround?

Only setting NoWarn, but that feels wrong.
