Move the example config to example.config.json

Avoid potential issues with people putting their actual secrets into a file tracked by git.

config.json is already in .gitignore, so should be good there.

Ehh, I think there's always going to be issues with people putting creds in files. Even with a name change, it's still just as easy for users to put their secrets in the example.config.json file and never rename it, which defeats the purpose

Unless others have strong opinions on this, I plan on just keeping it the way it is. I usually just have a duplicate json file active.config.json or something similar that I use
