Change "neopixel" references to use RGB LED naming (#10225)
* fix(rgbled): fixes core rgbledWrite()

* fix(rgbled): fixes examples - rgbledWrite()

* fix(rgbled): fixes variants commetaries - rgbledWrite()

* fix(rgbled): examples and doc - use RGB_LED naming

* fix(rgbled): variants - use RGB_LED naming

* fix(rgbled): other places for RGB LED naming

* fix(typo): cores - rgbLed instead of rgbled

* fix(typo): examples - rgbLed instead of rgbled

* fix(typo): variants commentaties - rgbLed instead of rgbled

* fix(rgbled): bad file name

* fix(typo): typo and commentaries

* fix(rgbled): deprecating neopixelWrite()

* fix(rgbled): use RGB LED naming

* fix(rgbled): document formatting

* fix(rgbled): neopixelWrite() is now deprecated

* fix(rgbled): removed attribute in wrong place

* just a git push test

* restart git bash test

* ci(pre-commit): Apply automatic fixes

* removed wrong test file

* fix(rgbled): new Arduino style depreacted attribute
