The `chat` example is empty

[ClementNerma]

There is a chat.rs example file in the repository but it is empty:

#[tokio::main]
async fn main() {
    unimplemented!();
}

Why put an empty example file that contains nothing (genuine question)?

[Darksonn]

No idea. It should be removed.

I submitted a PR with it back then https://github.com/tokio-rs/mini-redis/pull/32/
