✏️ Editing: palette-colorpicker.js

 * Script for our custom colorpicker control.
 *
 * This is copied from wp-admin/js/customize-controls.js
 * with a few tweaks:
 * 		Removed the hue picker script because we don't use it here
 * 		Added the "palettes" argument in wpColorPicker().
 *
 * @since Twenty Twenty-One 1.0
