[FIX] website_slide: correct spacing in quiz answer info

How to reproduce it:
- Install website_slides
- Go in the course "Basics of Gardening"
- Do the test "Test you knowledge" in fullscreen mode
- The information displayed about your answer is glued to the information icon

This fix the problem by adding space between the icon and the text.

Technical note: Although the html has not changed, the problem was not present
in previous version because the rendering process was not removing all spaces
which is now the case.
