Link to Princeton Courses from Recal

[panchr]

The idea here is that instead of linking to the Registrar, we can link directly to Princeton Courses from the "info" button:

This shouldn't be too difficult as Princeton Courses has a straightforward URL format of https://www.princetoncourses.com/course/{course_id}( e.g. https://www.princetoncourses.com/course/1184004171). Essentially, this just requires changing the URL that is used as the link for the info button.
