[FIX] website_slides: add style to the side bar container

Reproduction:
1. Install Website and eLearning
2. Add new language Dutch
3. Modify the course responsible’s name as “Gertjan Kleinbloesem” in
eLearning
4. Open the course page in the website app and switch to Dutch, the
responsible name is over flowed

Reason: The background container doesn’t adapt to the length of the text

Fix: Add text break to the responsible's name so it won't break the
style
