Add PatchBot stuff

These are a little different than the ones we were using privately
before and will require some one-off hopefully straightforward
copy-pasting for existing developers. But hopefully this'll remove some
friction from using the thing across the board.

I'd still like to investigate smoother auth methods in the future. The
SSH key idea seems like a good one, but there's some annoying obstacles
there. There's also the idea of having the Discord bot send people
tokens. For now, it's still just manual, which is probably good enough
for quite a long time, to be honest.

This also includes the Sorse Tecknoledgy Committy Discord link, because
I've kind of not done well to advertise the existence of that thing. It
has always been technically open the public, except many people probably
don't know it's there.
