Keyboard: Add basic support for the YD68 / YD68v2 PCBs. (#4020)

* Add basic support for the YD68 / YD68v2.

Keymap and WS2812 underlighting work. Capslock LED should work, though I don't have one populated to test. Backlight LEDs are not set up, as they're not on a hardware PWM pin, could be set up as software.

* Fix Imgur link

* Fix default keymap to match the stock firmware

* Fix the Hardware Supported line and add a short description
