Deploy through GitHub Action

[Logerfo]

I think it's possible to write a GitHub Action workflow that allows people to just fork this repository as is, set their environment variables and run the action to deploy their own bot without even need to clone.
Docker may or may not be used. It may be useful, but I don't think it's necessary. It's usually slower as a whole, but image caching might help to reduce fixed time costs.
