missing webSocketImpl

[yovanoc]

I think you should add this webSocketImpl directly to the generated code otherwise for those using subscriptions there are error by default just after generating.

import WebSocket from "isomorphic-ws";

// ....

const client = createClient({
   webSocketImpl: WebSocket,
    url: String(options[0]),
    connectionParams: Object.fromEntries(new Headers(options[1]?.headers).entries()),
  });
