Checklist

General

• I tested all changes and their related features with all corresponding user types on a test server.
• I chose a title conforming to the naming conventions for pull requests

Motivation and Context

The documentation contains several screenshots that do not reflect the current state of the code editors in Artemis.

Description

I updated the screenshots that featured the editor in a meaningful way.

Steps for Testing

1. Deploy on a test server
2. In the footer, click "About", then on 6. Exam mode, go to both the page for "Students" and "Instructors" and check that the screenshots are up to date. (You may have to clear your cache if they are not.)
3. Review the other screenshots that were updated. You can see them in the diff of this PR or in the documentation. The pages/sections affected are:
