text: Title: Enhance BDD support (GIVEN/WHEN/THEN) for French language
  Body: Hi,
  
  According to the Gherkin Syntax, there's a lot of ways to translate the BDD keywords in French.
  Cf: https://cucumber.io/docs/gherkin/languages/
  
  As an exemple, GIVEN => 16 possibilities
  
  ![image](https://github.com/robotframework/robotframework/assets/996732/b8ed00e2-166c-47d4-bba2-571086682b91)
  
  Currently, only one seems implemented in Robot Framework:  'Étant donné'
  
  This has impacts:
  - emphasis on capital letter is not easy to type
  - this involves sometimes to midy the name of the step so that the general meaning of the sentence is correct
  
  To resolves this, will it be possible to implements all the possibilities ?
  Or at least  "Etant donné",  "Etant donné que", "Étant donné que".
  
  Regards
