[types] `Response.body` does not extend `ReadableStream`

The browser’s Response.body is ReadableStream.

Based on fetch.d.ts Response.body of undici is just ControlledAsyncIterable.

The code below is valid and workable. However, because of fetch.d.ts I see the warning in my IDE (IntelliJ IDEA).

const response = await fetch(url);

/** @type {ReadableStream} */
const body = response.body; // Warning: "Initializer type ControlledAsyncIterable is not assignable to variable type ReadableStream"
body.getReader();

const response = await fetch(url);

const body = response.body;
body.getReader(); // Warning: "Unresolved function or method getReader()"

Ah your PR did it! It was just not tagged with “closes #issue” so this would get closed automatically.
