`--kblight` does not work on Framework 16 - should call qmk_hid

[hms5232]

I'm using Laptop 16 with keyboard and num pad.

I notice that every time I ran framework_tool --kblight to get or set the backlight, it always return InvalidCommand:

hms5232@Laptop-16-AMD-Ryzen-7040-Series:~$ sudo ~/bin/framework_tool --kblight
[ERROR] EC Response Code: InvalidCommand
Keyboard backlight: Unable to tell

After searching web and issue, I can't find the solution or related reports, so submit an issue.

English is not my native language; please excuse typing errors.

Framework 16 keyboard is not connected to the embedded controller.
It's a standalone USB keyboard.

You can use qmk_hid via --backlight or qmk_hid via --rgb-brightness.
See: https://github.com/frameworkcomputer/qmk_hid

In theory I could hook up --kblight to qmk_hid to make it work automatically. Hmm
