Notes when updating to 1.2-preview2

• When you reference WinAppSDK 1.2 from a project you might see an error similar to: "Detected package downgrade: Microsoft.Windows.SDK.BuildTools from 10.0.22621.1 to 10.0.22000.194." To resolve, you can update the project’s reference to a more recent and compatible version of Microsoft.Windows.SDK.BuildTools, or simply remove the reference from your project to implicitly reference a compatible version.
• Starting with WinAppSDK 1.2-preview2, .NET 5 is no longer supported and C# apps will require a minimum version of .NET 6.
