Github Actions

The following workflows are supported.

A pre-generated Heroku App
A Heroku API key. It can be generated under your Account Settings
Three Heroku config vars:
- DATABASE_URL: It will be created automatically when the PostgreSQL add-on is added.
- PHX_HOST: if your app name is acme, the value of this var is: acme.herokuapp.com
- HEALTH_PATH: Health path (eg: "/_health")
- SECRET_KEY_BASE: use the mix phx.gen.secret to get a new secret and set it as the value of this var.

Defining two Github secrets to hold the value of Heroku API key and Heroku app name:
- HEROKU_API_KEY
- HEROKU_APP_NAME
If you plan on using WebSockets, the timeout for the WebSocket transport needs to be decreased in lib/hello_web/endpoint.ex.
```
socket "/socket", HelloWeb.UserSocket,
  websocket: [timeout: 45_000],
  longpoll: false
  ...  
```
otherwise, leaving it set to false as default.
