[Feature request] xstate/store allow naming enqueued effects for tests

[sporto]

For testing using store.transition it would be very useful if effects could be named.
Taking this example https://stately.ai/docs/xstate-store#pure-transitions
At the moment effects contains Function, which is not very useful in tests.
It would be great if test could asserts what effects are being run.

Something like (note the second parameter to enqueue.effect:

const store = createStore({
  context: { count: 0 },
  on: {
    inc: (context, event: { by: number }, enqueue) => {
      enqueue.effect(() => foo(), "fooEffect")

      return {
        ...context,
        count: context.count + event.by,
      };
    },
  },
});

Then on the test

const snapshot = store.getSnapshot();

const [nextState, effects] = store.transition(snapshot, {
  type: 'inc',
  by: 1,
});

expect(effects).toContain("fooEffect")
