[Keyboard] Update COD67 support to complete it and add a personal map (#7291)

* Update docs for default keymap

* Update COD67 docs with fixes and macOS details

* Add a personal COD67 2-layer map with RGB control

* Enable RGB, NKRO and change firmware format to bin

* Swap k0D and k48 to fix backspace on the top row

* Add RGB config and tidy up a bit

* Finish default map because merlin was full of bbq

* Whoops, rogue tabs

* Typo fix in the main COD67 readme

* Remove empty function defs in keymap

* Swap how the backspace key relocation happens

* Fix PRODUCT_ID and add a link to software PWM docs

* Disable NKRO and bootmagic and enable mouse keys

* Better header guard

* Whoops, forgot to remote the #endif

+The COD67 supports really nice RGB underglow which you can see through the mid diffuser. I've put control for that on layer 1, along with reset on `Space`, backlight toggle on `Enter`, and the function row. The board supports all of the QMK RGB effects.
+
+Look at the excellent [RGB Lighting](https://docs.qmk.fm/#/feature_rgblight) docs on the QMK site for more controls.

 Hardware Supported: Gray COD67  
 Hardware Availability: [Zfrontier](https://en.zfrontier.com/products/cod67)  
 
-At this time, flashing ONLY works on Windows systems. 
+## Bootloader mode

+To put in bootloader mode, hold the `Esc` key while plugging in the USB cable.
 
-The COD67 will show up as a drive. 
+## Making firmware
 
 Make example for this keyboard (after setting up your build environment):
 
-    make gray_studio/cod67:default:bin
+    make gray_studio/cod67:default
 
 See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).
 
-Rename the resulting `.bin` file to `cod67.bin`.
+## Flashing in Windows
 
-Drag and drop `cod67.bin` to the drive, overwriting the previous `cod67.bin` stored on it. 
+After putting your COD67 in bootloader mode, it will show up as a drive.
 
-Press the `Esc` key again to reset the board. You are now ready to type!
+* Rename the resulting `.bin` file to `COD67.BIN`.
+* Drag and drop your new `COD67.BIN` to the drive, overwriting the previous `COD67.BIN` stored on it.
+* Wait a few seconds for it to write. The caps lock LED flashes rapidly while writing.
+* Press the `Esc` key again to reset the board. You are now ready to type!
+
+## Flashing in macOS
+
+After putting your COD67 in bootloader mode, it will show up as a drive.
+
+* Rename the resulting `.bin` file to `COD67.BIN`.
+* Drag the existing `COD67.BIN` file from the drive to the Trash in Finder.
+* Empty the Trash in Finder. It's important you do that due to how macOS handles hidden `.Trashes` on removable drives. It needs to be empty to free up flash space.
+* Drag and drop your new `COD67.BIN` to the drive.
+* Wait a few seconds for it to write. The caps lock LED flashes rapidly while writing.
+* Press the `Esc` key or eject the drive in Finder to reset the board. You are now ready to type!
 
 ## Notes
-The backlight pin is attached to a non PWM pin `D4` so backlight is only on/off.
