Add the functionality that the preprocessor also translates/replaces arguments in `DocString`.

This is a Documented Cucumber Feature:
https://github.com/yuyijq/cucumber/wiki/Multiline-Step-Arguments#substitution-in-scenario-outlines
Improvements
linter sucks
Adjust feature file
Add Step Definitions
