Fn key modifier missing in Modifier Keys for Karabiner DriverKit VirtualHIDKeyboard 1.8.0

[gaabora]

Hello!

I'm using the latest beta of Karabiner-Elements (v15.3.30), and I noticed that the Fn key modifier is missing for the Karabiner DriverKit VirtualHIDKeyboard 1.8.0 device under:

System Settings > Keyboard > Keyboard Shortcuts... > Modifier Keys

It seems like Fn support might not be implemented for this driver yet.
Would it be possible to add support for the Fn modifier in a future release?

Thanks for the great tool and all your continued work!
