AppletDelegate: Allow removing unsupported widgets
Otherwise, in Plasma 6, there is no way to remove the widget, which may prevent installing a newer version.
An supported widget can be highlighted, but the icon will appear disabled and it cannot be dragged. The uninstall button will now appear also.
For testing, try installing my Thermal Monitor (olib) widget in Plasma 5, and then switch to Plasma 6. It should be possible to remove it. This makes it possible to install my newer Plasma 6 widget (which still appears unsupported, and I will investigate that).
