[Keyboard] YMDK YMD40 v2 (#11835)

* [Keyboard] YMDK YMD40 v2

* fork default keymap into default and factory

- factory keymap is as assigned by the extracted JSON provided by the vendor
- default keymap is based on the Planck

* add AUDIO_SUPPORTED rule per drashna

* modify factory keymap's readme

Recommend users copy the default keymap instead.
