Add dom.iterable and dom.asynciterable in compiler options

[reosablo]

On the current environment, dom.iterable and dom.asynciterable don't seem to be active in the code editor.

for (const div of document.querySelectorAll("div")) { }

Type NodeListOf<HTMLDivElement> must have a [Symbol.iterator]() method that returns an iterator.

for await (const chunk of new ReadableStream()) { }

Type ReadableStream<any> must have a [Symbol.asyncIterator]() method that returns an async iterator.

The workaround for this issue is to add reference directives.

/// <reference lib="dom.iterable" />
/// <reference lib="dom.asynciterable" />

The Deno docs show an example configuration like this.

{
  "compilerOptions": {
    "target": "esnext",
    "lib": ["dom", "dom.iterable", "dom.asynciterable", "deno.ns"]
  }
}
