Added two new bot conversation types:
Broadcast: only those who execute the "/chatgpt broadcast" command can talk to the bot but all users of the server will be able to see the conversation.
Full: When someone runs the "/chatgpt full" command everyone will be able to communicate with the bot and see the replies.

The config has been updated, it is recommended to regenerate it.

The permission system has been changed:
/chatgpt | /chatgpt single -> minecraftgpt.command.single
/chatgpt broadcast -> minecraftgpt.command.broadcast
/chatgpt full -> minecraftgpt.command.full
