Add and fix French translation.

Hey Gaëtan, with the accents, I presume you're seeing most STT services returning transcripts without them?

Happy to go with what works in the most cases for now. But wondering if this is something we should be mindful of when building out improved translation layers? Should we support both accented and non-accented forms?

@krisgesling I got weird behavior with the accents, not sure why (yet), for example I'm not able to stop the speaking.

Is the STT returning non-accented strings? Or even with accents in the utterance string you are still seeing problems?

@krisgesling seems to work with the accent now, I'm confused... I reverted all the changes related to the accents in my PR.

It worked by voice as well...

Yeah weird... I'm guessing that this will be a problem with certain STT's though. So good thing for us to think about in the future.

Edit: same with hyphenated words, I can easily see scenarios where some engines return hyphenated, others return with a space.
