`FakeTime` does not mock `node:timers` methods

**Describe the bug**

[`FakeTime`](https://jsr.io/@std/testing/doc/time/~/FakeTime) does not mock [`node:timers`](https://nodejs.org/api/timers.html) methods.

**Steps to Reproduce**

1. Create `index.js` file
```javascript
import { assertSpyCalls, spy } from "jsr:@std/testing/mock";
import { FakeTime } from "jsr:@std/testing/time";
import timers from "node:timers/promises";

Deno.test("with timers", async () => {
const init = async (cb) => {
await timers.setTimeout(1000);
cb();
};

using time = new FakeTime();

const cb = spy();
init(cb);

time.tick(1000);
await time.runMicrotasks();
assertSpyCalls(cb, 1);
});

Deno.test("with setTimeout", async () => {
const init = async (cb) => {
await new Promise((r) => setTimeout(r, 1000));
cb();
};

using time = new FakeTime();

const cb = spy();
init(cb);

time.tick(1000);
await time.runMicrotasks();
assertSpyCalls(cb, 1);
});
```
2. Execute the command: `deno test index.js`
3. See error
```
running 2 tests from ./index.js
with timers ... FAILED (3ms)
with setTimeout ... ok (16ms)

ERRORS

with timers => ./index.js:5:6
error: AssertionError: Spy not called as much as expected:

FAILURES

with timers => ./index.js:5:6

FAILED | 1 passed | 1 failed (27ms)

error: Test failed
```

**Expected behavior**

FakeTime mock the [`timersPromises.setTimeout([delay[, value[, options]]])`](https://nodejs.org/api/timers.html#timerspromisessettimeoutdelay-value-options) method.

**Actual behavior**

FakeTime does not mock the `timersPromises.setTimeout()` method.

**Environment**

- OS: Ubuntu 25.04
- deno version: 2.8.2
- std version:
