[C2] Add URL confirmation when deleting an access URL #6272
Description
In /main/admin/access_urls.php, when deleting an existing URL, the confirmation message is too light. There should be a validation on the URL to be deleted (asking the user to type or copy-paste the URL to confirm the request) as the impact of deleting a URL can be massive.
See the procedure to delete a course in /main/course_info/maintenance.php and /main/course_info/delete_course.php for an idea on how to implement this.
