Make it easier to find tb-manual
It is hard to find tb-manual.torproject.org from www.torproject.org. I found only one link, anywhere. On the webpage for downloading, scroll halfway down to find it in a sentence in the middle of similar looking paragraphs. I found the manuals on 2019.www.torproject.org from the www.torproject.org Documentation heading much faster than I found tb-manual.torproject.org.
It is easy to find support.torproject.org because it is on every page in the heading.
