Add an H1 heading and an admin notice to display on the Widgets screen when JS is not available. Invite the user to either install or activate the Classic Widgets plugin, as that plugin provides basic functionality without JS. Props afercia, nihar007, huzaifaalmesbah, joedolson, matthewfarlymn, bvreeman22, bosskhj, devmuhib, shailu25, joedolson. Fixes #58738.
