Display the course-level tags applied to the course in the course comparison dashboard

User Story
As a course delivery team member, I want to be able to see what course-level tag(s) have been applied to each course in the list of courses I'm comparing once I've applied a course-level filter, so that I can easily see how each of the courses returned in the results have been tagged (this is especially needed for when a user applies a filter with multiple values, so the user knows when both or only some values apply to a particular result).

Acceptance Criteria
Given I have access to the Course Comparison dashboard
When I have applied a course-level tag filter to the Course Comparison dashboard
Then I can view the course-level tags applied to each course in the results
And when there are more than N characters to be shown, we truncate this list (but allow the user some way of viewing the whole list (maybe on hover or clicking to expand/collapse).
