Description

• Language: fr_FR
• Phrase: "Blackbox activée"
• Phrase: "Blackbox désactivée"
• Phrase: "Buzzer activé"
• Phrase: "Buzzer désactivé"

It is better to keep "Blackbox" and "buzzer" because we use them in french. The translation in french would be comic/weird

Help make EdgeTX better!

• (optional) I can help reviewing the new sounds once they're generated.

"Buzzer active" and "Blackbox active" is present in most languages, but not the deactivate form. "Buzzer off" is present in a couple though. As is "Blackbox erase".
