If a site does not have the Gutenberg plugin enabled, the editor settings endpoint is unavailable. We set a default color palette and gradients to enable customizing block styles.
Ensures preset styles are loaded--e.g., utility classes for colors.
Bring our copy of this private utility up to date.
Embrace new abilities of this private function copy.
Include default color utility classes. This is typically added by WordPress' admin via PHP. The manual addition is necessary for sites without the GutenbergKit plugin, which do not provide editor settings and theme styles.
Even if the theme style preferences is enabled, we must apply the default styles if: 1. The theme provides no style via a block.json; 2. Or the site lacks the experimental Gutenberg REST API endpoint providing editor settings and styles.

The changes here update this copy of a private Gutenberg core function to match the latest version.

These utility classes are generated by WordPress PHP, but are not present if a site does not have the Gutenberg plugin activated and therefore does not have the experimental editor settings REST API endpoint.
This copy serves as a fallback for those sites for the time being.
