Add a prominent reference to discuss.ipfs.io from the docs page(s)

(suggested by @drozdziak1 at https://discuss.ipfs.io/t/why-isnt-this-site-easily-accessible-from-the-main-page/1398)

At the moment ipfs.io doesn't mention the forums at discuss.ipfs.io. We should add a link from the docs page, and possibly elsewhere, encouraging people to use those forums.

Make the info under "Community" on https://ipfs.io/docs/ match the info at https://github.com/ipfs/ipfs/blob/master/README.md#project-and-community -- most importantly, remove references to ipfs/faq and ipfs/support, which have been deprecated and redirected to discuss.ipfs.io

We could just add a link in the top navbar otherwise, hard to make it easier to find than that.

@victorbjelkholm That would be ideal, thanks guys

[flyingzumwalt]

Yeah. Let's add it to the navbar too, but we should also update the Community section on the Docs page. It's got out of date info, pointing to deprecated repositories.

Bumping this. We should have a prominent HOW TO GET HELP item that send people to discuss. While there is extensive documentation on how to contribute and help others, there is no reference to how actually get help from others.
