Add the attribute `role="alert"` on 12 instances of admin notices that are injected into the DOM using JavaScript. The `role="alert"` attribute allows screen readers to recognize the addition to the DOM and announce the errors to users. Props afercia, cyrus11, rcreators, joedolson. Fixes #47111. Built from https://develop.svn.wordpress.org/trunk@58455 git-svn-id: http://core.svn.wordpress.org/trunk@57904 1a063a9b-81f0-0310-95a4-ce76da25c4cd
