Old version of code example in the docs

[kota-yata]

I was looking at the certificate example at the quinn docs and realized it was not up to date.

It shows that client configuration is done with following code:

fn configure_client() -> ClientConfig {
    let crypto = rustls::ClientConfig::builder()
        .with_safe_defaults()
        .with_custom_certificate_verifier(SkipServerVerification::new())
        .with_no_client_auth();

    ClientConfig::new(Arc::new(crypto))
}

but this only works before this commit, when QuicClientConfig was not yet introduced.

Other example code in the docs might be outdated too although I haven't tried them all.
