Laurel Fulford dcf18e9114 Toujours: Minor updates to the Gutenberg styles, including:
* Reorganize styles a bit, consolidate header styles, and delete empty selectors
* Update editor colour palette to match theme's colours
* Remove  styles for pre and code blocks in editor; doesn't look identical to the front-end but they blocked the text from being edited
