ANN: OnlinePackage 0.2

Now works with GitHub actions instead of travis. Will automatically generate and upload SSH keys to your GitHub repos. This is necessary to host documentation. This version is much better tested than the last one.

I considered adding a feature to upload CodeCov tokens as well, but it looks like CodeCov is on its way to not requiring them from GitHub actions.

Y’all I suffered a lot for this one. Hopefully it makes your lives easier?
