fix(ext/node): support ipv6 host in node:http

[0f-0b]

Closes #21864. Full reproduction of the bug:

import { once } from "node:events";
import { request } from "node:http";

await using _server = Deno.serve({ hostname: "::1" }, () => new Response());
const req = request("http://[::1]:8000").end();
const [res] = await once(req, "response");
console.log(res.statusCode); // should print `200`

Thanks, could you add a unit test @0f-0b?
