Hi, I just found that JGiven has the ability to translate words of the Gherkin Language. So here I am, contributing for the French Nation !

Hi, thanks for your contribution. It is greatly appreciated.

However, may I ask you to open a PR for the addition? That would also likely speed up the time until it gets into master, as I am rather busy right now.
