Frequent timeout errors with Node 20

[Rinse12]

Hey y'all. We've used this library with different NodeJS versions, and on the 20 LTS version, kubo-rpc-client throws timeout errors frequently whenever an RPC function is called. You don't have to call a specific function, it throws randomly.

An example code to produce:

import { create, urlSource } from "kubo-rpc-client";

const topicToTest = "test-topic" + Math.random();
(async () => {
  const kuboClient = create("http://localhost:5001/api/v0");
  let subscriptionCount = 0;

  setTimeout(async () => {
  const subscribedPubsubTopics = await kuboClient.pubsub.ls();
    if (!subscribedPubsubTopics.includes(topicToTest)) {
      await kuboClient.pubsub.subscribe(topicToTest, () => {}, {
        onError: (err) => console.error(`Failed to pubsub subscribe`, err),
      });
      subscriptionCount++;
      console.log(
        `Subscribed to topic (${topicToTest}) for the ${subscriptionCount}th time`
      );
    }
  }, 5000);
})();

Randomly you'd get a timeout error that looks like this

Failed to pubsub subscribe TypeError: terminated

Same for me. Is it linked to the "timeout" option (L471)? https://github.com/ipfs/js-kubo-rpc-client/blob/5c7e42ef02e9c9f8a509905fb22589107b158d2c/src/index.ts#L466-L476 The absence of documentation does not help :confused: (related to #113)

I've tested on Node 20, 18, and 16. 16 Doesn't have this issue, so I guess it's a compatibility problem between kubo-rpc-client and native fetch in node 18+
