french translation

There is no french translation yet. Maybe I could be of some help?

i'd put the fr.json in translations and modify the guac-manifest.json this way

Unfortunately, injecting those files in the guacamole-auth-totp-1.2.0.jar will conduct to a fail for the TOTP => no 2FA during the loggin process and no way to go back to a normal situation, even after having restored the guacamole-auth-totp-1.2.0.jar file.

I'm just currious and trying to help.

Thanks again for this superb tool.
