docs: upgrade some links to https

We're in 2022 now, and HTTPS is available in a lot more places in the
past. Let's upgrade some links, to protect the privacy of our readers.

The links that are left either don't support HTTPS, or are simply dead
and needs to be updated anyway. That's besides the scope of this
merge-request, so I'm leaving that for someone else.
