[Plugin: Comment Validation Reloaded] changes warning messages

Hello,
thanks for this great plugin 🙂
I trying to translate the different messages in french, but I didnt find the file where “This field is required.” message is located.
I’ve found something in the validate.js file but nothing change.

Could you help ?

Thank you so much.
