Studio: removing static rendering notes/comments from course rerun template

cms/templates/course-create-rerun.html

-<!--
-
-DESIGN/UI NOTES:
-
-* changed tip-based UI text to have is-hidden/is-shown stateful classes rather than is-hiding/is-showing
-* create-course and new-course prefixed classes have been changed to use rerun-courses
-* changed form <input /> elements to <button> elements
-
-- - -
-
-TODO:
-
-* sync up styling of stateful classes
-* need to add support for allow_unicode_course_id in real view's template
