French translations for captions

[Michelle D'Souza]

Hi Alex,

Charly corrected the french translations for the captions files in the demo. We have since changed to web vtt  format and renamed the json files so they can be used as transcripts. This change made applying his corrections difficult. I've pushed a branch to my repo containing the properly translated files.

Could you fix the captions and transcripts using these files?

Thanks!

Michelle
