CA66 R1/R2 Cleanup (#6678)

* fixup readme to adhere to QMK standards and to also have more information

* use pragma once

* strip out the custom bootmagic lite routine as it is the same as QMK's default bootmagic lite routine. Also add the caps lock led indicator

* turn on bootmagic lite

* update default keymap

* Update keyboards/playkbtw/ca66/ca66.c

Co-Authored-By: fauxpark <fauxpark@gmail.com>

* remove lines 4 thru 37 and add bootloader
