Add an extra prerequisite - ruby2.x-dev in docs/README.md (#1820)

* Add an extra prerequisite - ruby2.x-dev

Trying to install Jekyll on my Linux (Ubuntu 16.04) machine failed because ```ruby 2.x``` was installed and ```ruby2.x-dev``` was not. I spent a lot of time trying to figure it out (I'm no ruby expert) but installing the ```ruby2.x-dev``` solved my problem.

* Add a note for Ubuntu users
