Description

When you use settings.color.defaultPalette, settings.color.defaultDuotone and settings.color.defaultGradients to turn off the WordPress default options for these supports the css variables still appear in the DOM on inspection. I would expect these to be removed if they've been disabled by the theme and aren't available to the user in the block editor.

Step-by-step reproduction instructions

Set settings.color.defaultPalette, settings.color.defaultDuotone and settings.color.defaultGradients to false
inspect the front-end of your application. You should see the variables for the defaults on the body element. One example I'm seeing is the default gradient --wp--preset--gradient--blush-bordeaux
