Why do we want to ignore this error?

The code below checks if the kick message contains an outdated version message then emits a new error, but it's not essential. And since the reason field is actually a JSON chat message it's still valid for the server to send a plain string (ie "hello world" as opposed to {"text":"hello world"}) as opposed to JSON, as the chat parsing code will accept it (but simply calling JSON.parse("hello world") will throw). So to correctly parse it we would have to import prismarine-chat and parse it with that.
