Description

If I disable everything relating to colors in theme.json, the panel still shows up on blocks that support it, such the group block.

Step-by-step reproduction instructions

1. In a block theme, set theme.json like this:

{
    "version": 2,
    "settings": {
        "color": {
            "custom": false,
            "customDuotone": false,
            "customGradient": false,
            "defaultGradients": false,
            "defaultPalette": false,
            "background": false,
            "defaultDuotone": false,
            "text": false
        }
    }
}

2. In the block editor, ad a group block. Notice you'll still see a Color panel in the sidebar, even though you can't do anything with it. Interestingly it shows a "background" option that opens a popover with nothing inside it.
