Offer lecturers and moderators the option to edit tags
I am on the tag cloud view. As an instructor or moderator, I would like to be able to edit individual tags to improve the presentation and understanding of the tags.
Acceptance Criteria:
- I see a Settings icon in the header on the right.
- There I see a toggle: "Edit tags".
- I activate the toggle.
- A list of all tags in alphabetical order is displayed.
- The list is editable.
- I edit a few tags and save the list.
- The tag cloud now shows the tags in the revised form for all users.
