Update Tor Browser manual + support pages
We should make sure our manual and support pages are updated with screenshots of our new UI as well as the copy.
We should pay special attention for decisions we made in relationship to the copy, for instance the bridges settings page, like the terms build-in bridges for Pluggable Transports.
