Make "Getting Help" documentation much more prominent

[Shai Berger]

Issues like ​https://github.com/django/djangoproject.com/issues/947 show up very often, I think they are more common than actual website issues. Each and every time we close such an issue with "go get help in proper channels", it's a little failure -- for the submitter, of course, but also for us. I think we can try harder to make the correct channels more prominent. Here's a list of potential action items:

1. The whole "Getting Help" section on the documentation front page sits only in the side bar, below obviously-less-interesting stuff like the navigation tools. It is easy to miss it entirely.
   1. We could make it one of the first sections in the list -- I suspect that the first three sections should be "First steps", "Getting help", and only then "How the documentation is organized".
   2. I'd also consider making a link to .../faq/help/ float on the documentation page, like the language and version selectors do now.

2. The tutorial mentions "where to get help" in an admonition very close to its beginning, but then it is never repeated, and it is easily forgotten by the time anyone actually needs it.
   1. Make the admonition link to the faq, and mention the links to get help which are present on every documentation page
   2. Repeat the admonition, at least once on every tutorial page

3. The ticket-creation form for the Django code -- the one I'm filling in now -- has a list of things for a (first-time) submitter to consider, under the heading "Please read this first"; I believe this list greatly reduces the amount of support-tickets filed on this tracker. A similar thing can be done for the djangoproject.com repo using ​issue templates.
