fuel-core node cleanup doesn't work in bun

[nedsalk]

When using bun v1.1.33, trying to call cleanup on the return of launchTestNode results in the following error:

282 |       }
283 |       childState.isDead = true;
284 |       removeSideffects();
285 |       if (child.pid !== void 0) {
286 |         try {
287 |           process.kill(-child.pid);
                ^
RangeError: The value of "pid" is out of range. It must be a positive integer.

There is the issue oven-sh/bun#8787 which documents an additional occurrence of this problem, so it might not be our fault.

Run the following to reproduce:

mkdir bun-test && cd bun-test && bun init -y && bun add [email protected] && echo 'import { test } from "bun:test";
import { launchTestNode } from "fuels/test-utils";

test("test", async () => {
    using launched = await launchTestNode();
});' > failing.test.ts && bun test
