Comment (by peterwilsoncc):

 There is a [https://github.com/WordPress/gutenberg/pull/33793 pull request
 in progress] for this on the Gutenberg repository.

 The reported error on line 267 (selector list in `:not()`) is a false
 positive as the validator is for CSS 3 and `:not()` began supporting
 selector lists in CSS Level 4. All browsers supported by WordPress support
 the feature. https://caniuse.com/css-not-sel-list

 The reported error on line 2283 is a genuine positive: `width: none` is
 not valid.
