Telegram Bot plugin -> French buttons

Hey, I noticed that there are buttons written in French in the TelegramService file : 

```
if (!item.Inventory.HasValue || item.Inventory > 0)
{
    buttons.Add([
        InlineKeyboardButton.WithCallbackData("➕ Ajouter (1)", $"quick_add_{item.Id}"),
    InlineKeyboardButton.WithCallbackData("🔢 Quantité", $"add_{item.Id}")
    ]);
}
```
