- wsl-appx isn't available outside of being included by .kiwi file,
so adding it back, but using config.sh to remove it once done

- Removing wsl-appx inclusion from .kiwi file and incorporating
into config.sh

- config.sh will pull in MAJOR_VER and SP_VER from wsl-appx
/usr/share/wsl-appx/DOTsettings to update /etc/YaST2/products.yaml
* This will only happen if opensuse is NOT detected in os-release
