Update WpfAutoGrid to Net 5 / 6 / 7

Hi, colleagues.

Can you update WpfAutoGrid to Net7.0?

Meanwhile as a workaround see the .NET supported version here:

• GitHub: https://github.com/budul100/WpfAutoGrid.Core
• NuGet: https://www.nuget.org/packages/WpfAutoGrid.Core

You'll need to change the namespace import afterwards:
xmlns:wpfAutoGrid="clr-namespace:WpfAutoGrid;assembly=WpfAutoGrid
->
xmlns:wpfAutoGrid="clr-namespace:WpfAutoGrid;assembly=WpfAutoGrid.Core
