Unable to remap numeric keypad (NumPad) keys

Issue type

UI bug

Bug description

When I try to remap the numeric keypad keys, MuseScore actually just remaps the regular number keys. For example (since I find the default mapping counterintuitive) I want e.g. '4' on the keypad to be a quarter note. When I remap it, hitting '4' on the keypad doesn't return 'Num4' as it should, but instead '4'. No combination of modifiers gets MuseScore's remapper to recognize Num4...

I've confirmed that other applications that differentiate between keypad and number-row do recognize the difference, such as Pro Tools. Also, Karabiner EventViewer also returns different codes for keypad vs number-row. So I don't think my system has a problem.

This is MuseScore 4.0.2 on two Macs ~ M1 Macbook Air with Ventura 13.3, and i9 iMac with Monterey 12.6.3.

Steps to reproduce

1. Open Preferences->Shortcuts
2. Find a shortcut to modify, and double click it to open the "Define shortcut" popup
3. Press a numeric keypad key
4. You'll see that instead of e.g. "Num4", the value "4" is defined, which corresponds only to the number 4 on the number-row.
5. Close the dialog, and try to use the new shortcut via the number pad
6. Nothing happens.
