Automatically start the rails server

[Seifeldin7]

Currently, cypress-on-rails relies on manually starting the Rails server before running Cypress tests. Having a built-in mechanism to start the Rails server programmatically using rake tasks would be beneficial. This will simplify running specs, without needing another terminal. It's especially useful for CI.

This can easily be fixed by defining a simple procfile.
