[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.

+A 40% ortholinear keyboard with in-switch LED support, underglow, and USB Type C.
+
+* Keyboard Maintainer: [The QMK Community](https://github.com/qmk)
+* Hardware Supported: YMD40v2 PCB (ATmega32U4)
+* Hardware Availability: [AliExpress](https://www.aliexpress.com/i/32821953148.html), [ymdkey.com](https://ymdkey.com/collections/40-mini-diy/products/ymd40-v2-diy-kit-qmk-type-c-pcb-cnc-case-plate-for-40-mini-cute-mechanical-keyboard-similar-to-planck-layout)
+
+Make example for this keyboard (after setting up your build environment):
+
+    make ymdk/ymd40/v2:default
+
+Flashing example for this keyboard:
+
+    make ymdk/ymd40/v2:default:flash
+
+To reset the board into bootloader mode, hold the key at the top left of the keyboard while connecting the USB cable (also erases persistent settings).
