Update announcement priorities and icons for better clarity

Modify the AnnouncementCard component to change the 'error' type label and icon to 'Nouveauté' with a 'Sparkles' icon, and update the 'success' type to 'Important' with a 'Star' icon, aligning with user feedback for improved announcement categorization.
