French status translation to improve

[jodou92]

I find that some french status translation are confusing

status.held: Tenu
status.timed: Chronométré

In my opinion theses translations are literally correct but not really understandable for a French speaking contributor. I suggest to use instead :

status.held: Non publié
status.timed: Publication planifiée

I am going to make a PR for this

@jodou92 As the PR has been merged, I think you can close your issue :) Thanks for the french translation enhancement 🙌
