Lesson template - Stray pipe

[kathrynwp]

On lesson pages that are part of a course, there seems to be a stray pipe| displaying to the left of the module name, near the top left:

Examples

from: https://learn.wordpress.org/lesson/how-to-log-in-with-wp-admin/

from: https://learn.wordpress.org/lesson/introduction-to-wordpress-2/

---

Should this be removed, or is there some additional information intended to go to the left of the pipe? I don't think we need the course name there since it's already in the breadcrumbs at the top left. Couldn't find this anywhere in the Figma mockups.

Will be fixed as part of #2638
