Include Roslyn5000 code fixers and analyzer

Add a ProjectReference to CommunityToolkit.Mvvm.CodeFixers.Roslyn5000 (ReferenceOutputAssembly="false") and update the packaged analyzer entry for roslyn5.0 to point at the Roslyn5000 DLL. This ensures the Roslyn 5.0 code fixers are built and included in the package analyzers folder for roslyn5.0 compatibility.
