Fix for PositionSelectedCommand not working with custom Command

Files Changed:

1. MainViewModel in Demo.csproj
2. CarouselViewControl in CarouselView.FormsPlugin.Abstractions

Fixed the bindable property to correctly accept and return custom ICommand implementations, to work with Prism for example.

Awesome. Will merge this change.

I cannot use this in my current implementation as ICommand doesn't support type argument.

Could try fixing that if I knew where and how you need the typed argument
