Bundled Themes: Twenty Twenty block editor inserter is missing the `+`.

Fixes the disappearing `+` in the block editor when using the latest version of the Gutenberg plugin, by adding support for the native Gutenberg editor styles and removing `color: inherit;` from Twenty Twenty's style.css.

Props nrqsnchz, .
Fixes #49610.
