Extend documentation for Cucumber

[mucsi96]

The goal of this issue is to extend the current Cucumber documentation to cover every topic which was already covered in Nightwatch-Cucumber package documentation

You can find the markdown files here. https://github.com/mucsi96/nightwatch-api/tree/master/packages/website/src/data

These files are the source for documentation site

@mucsi96 nightwatch-cucumber was easier to use with compare to latest nightwat-api. Multiple issue i am facing on updating our existing framework with latest Nightwach and Nightwatch-api.
It is very difficult to use cucumber runner as nightwatch runner is disabled as cucumber runner does not give so much flexibility as compared to Nightwach runner. Dropping plan to upgrading to latest nighwatch with latest nightwatch-api. :-( .
Note :- Nightwatch runner is more powerful than cucumber runner.
