MST-698 Remove escaping for Proctoring Requirements email on course_name and proctoring backend name (#27500)

The course name can contain apostrophes and other special characters. The email template right now escapes every words. This is not desired because it can render apostrophes like #39;. Update the email templates so only second half of the email template is escaped
