Update readmdFrench.md (Arduino-IRremote#784)

I've updated my email address.
I get a few emails a week for this project but it goes to my old address which doesn't get a lot of attention

 Please only email me if it is more appropriate than creating an Issue / PR. I **will** not respond to requests for adding support for particular boards, unless of course you are the creator of the board and would like to cooperate on the project. I will also **ignore** any emails asking me to tell you how to implement your ideas. However, if you have a private inquiry that you would only apply to you and you would prefer it to be via email, by all means.
