[FW][FIX] website_slides: close fullscreen mode when translation
Current behavior before PR:
(In the case when Multi-languages are set up for the website.) The translation button does not work well with the e-learning fullscreen view. It completely closes the fullscreen view and opens the edition on a blank page.
Desired behavior after PR is merged:
To avoid this, we intercept the click on the 'translate' button and redirect to the non-fullscreen view of this slide with the translation mode enabled.
