desrosj 5259b18f50 Widgets: Add editor styles to the widgets block editor.
This updates the widgets screen to load the editor styles in the same way as the post editor. This combined with the package updates in [51198] and [51199] ensures that the blocks added to sidebars more accurately reflect what will be displayed on the front end of the site.

Props isabel_brison, noisysocks, andraganescu, audrasjb, jorbin, caseymilne, desrosj.
Fixes #53344. See #53388.
