1. Removed website key, reserved for official website. Social media such as Instagram have their own key (contact:instagram, already present). See https://wiki.openstreetmap.org/wiki/FR:Key:website 2/

2. Real name is "Pills" only. "Smash Burger" is the strapline. I won't open an edit war only for that so, as a compromise, I'm adding an official_name key and I'm removing alt_name key since now duplicate.
