Proj1009: Remove configuration for dropped rule

Some diagnostic rules are no longer supported or have been removed by the analyzer creators. Code that attempts to configure these rules should therefore be removed.

Non-compliant

Non-compliant code should simply be removed:

MSBuild files

<Project Sdk="Microsoft.NET.Sdk">

  <PropertyGroup>
    <TargetFramework>net10.0</TargetFramework>
    <NoWarn>RS1038</NoWarn>
  </PropertyGroup>

</Project>

.globalconfig and .editorconfig files

dotnet_diagnostic.RS1038.severity = warning

C# Source

#pragma warning disable RS1038 // Non-compliant

[SuppressMessage("Category", "RS1038")] // Non-compliant
public class SomeClass
{
}
