In https visualization add onion services
Feedback that we got from Frontdesk:
Machine translation: "I was reading this: http://4bflp2c4tnynnbes.onion/es/https/https-1/ (specifically the diagram) The diagram is quite good, it explains it excellently, however it would be quite nice to add a switch for the hidden services (.onion). What things can the hidden services see, because they don't need HTTPS because they are encrypted by default."
"Estaba leyendo esto: http://4bflp2c4tnynnbes.onion/es/https/https-1/ (especificamente el diagrama) El diagrama está bastante bien, lo explica de forma excelente, sin embargo estaría bastante bien que se añadiese un interruptor para los servicios ocultos (.onion). Que cosas pueden ver los servicios ocultos, debido a que estos no necesitan HTTPS debido a que están encriptados por defecto."
