[Package Issue]: Microsoft.DotNet.DesktopRuntime.6 - Order matters for Side-By-Side installations

Category of the issue

Side-By-Side installation.

Brief description of your issue

I have just noticed that while it is possible to first install Microsoft.DotNet.DesktopRuntime.6 and then Microsoft.DotNet.DesktopRuntime.8, it is not possible the other way round.

Steps to reproduce

winget install --exact --id Microsoft.DotNet.DesktopRuntime.8
winget install --exact --id Microsoft.DotNet.DesktopRuntime.6

Actual behavior

PS C:\Users\Marco> winget list | Select-String "Microsoft.DotNet.DesktopRuntime"
PS C:\Users\Marco> winget install --exact --id Microsoft.DotNet.DesktopRuntime.8
Found Microsoft .NET Windows Desktop Runtime 8.0 [Microsoft.DotNet.DesktopRuntime.8] Version 8.0.0
