Change copy from 'drafts' to 'courses' for unpublished courses

closes OUT-3664

Test-plan:
- Ensure `unpublished_courses` FF is enabled
- Open user dashboard as a user with at least one teacher enrollment
- Ensure the Unpublished section is titled `Unpublished Courses` rather
than `Unpublished Drafts`
- Confirm the same text change in the course tray
