By the time .NET 8 GA ships, .NET 6 MAUI projects will not be supported.
Remove .NET 6 support from our .NET 8 workloads.
A `Xamarin.Shared.Sdk.MultiTarget.targets` file has been added to update
the ref/runtime pack versions associated with the .NET 6 SDK. This file
will ship as part of the .NET 7 SDK but only be imported when using the
.NET 6 SDK. This should work around the need to add new and net7
versioned aliases of the `Ref` and `Runtime` packs. Adding this file to
`AfterMicrosoftNETSdkTargets` will ensure that it is imported last,
after all `KnownFrameworkReferences` that need updating are declared.
