Add new route `/my-courses` to redirect users to their courses page

Here's the patch which provides the new route /my-courses

How to test

- Make sure the module social_course_basic is enabled
- Apply the patch
- As an authenticated user, go to /my-courses

The expected result is that the user is redirected to their /user/{user}/courses page.

Sorry, there was a typo in the filename. No interdiff.
