 In [changeset:"48375" 48375]:
 {{{
 #!CommitTicketReference repository="" revision="48375"
 Accessibility: Media: Improve accessibility of the status and error
 messages in the Image Editor.

 - improves focus management by moving focus to the notices, if any, or to
 the first "tabbable" element
 - this avoids a focus loss and helps Braille-only and screen magnification
 users to be aware of the messages
 - adds an ARIA role `alert` to all the notices
 - uses `wp.a11y.speak()` to announce messages to assistive technology
 - this way, all visual users will see the messages while assistive
 technology users will get an audible message
 - uses `wp.i18n` for translatable strings in `wp-admin/js/image-edit.js`

 Props anevins, ryanshoover, antpb, SergeyBiryukov, afercia.
 See #20491.
 Fixes #47147.
