Bug 1922478 - fix the docs where they point to github. r=android-revi…

…ewers,npoon

I started off fixing the link to the APK repos, then realised that most of the other links and info on the page was also wrong. So i have fixed various bits :)
I've gone for codetribute for the link to the good-first-bugs as it's a nice friendly ui and people can browse around other projects if they want to.
