Feature Description

This issue should refactor CoreSiteBannerNotifications so that it uses the new datastore infrastructure to register and queue the notification. It should also incorporate a new "layout".

Do not alter or remove anything below. The following sections will be managed by moderators only.

Acceptance criteria

• The CoreSiteBannerNotifications component should be refactored so that it is registered and rendered (queued) using the new core/notifications datastore.
• This notification component should not be called directly (i.e. in BannerNotifications) but only via the generic getQueuedNotifications selector.
• The refactored component should not contain any business logic that hides it / prevents it from rendering. This logic should be contained in a callback function defined during registration.
• The component should not use the bloated BannerNotification component. Instead, it should be rendered using the new Notification component wrapper and a simpler "layout" component that solely encapsulates its structure and design.
