[Pedometer 4.0.1 ] Unable to trigger listen practice when screen_off

Please complete the following information for each phone and/or emulator you're experiencing this bug on:
- Device: Huawei P40 Pro
- OS: HarmonyOS 3.0.0 [compileSdkVersion 33]

### Describe the bug
Listen is often triggered when screen_on and I can get the number of steps. But once screen_off is no longer triggered.

### To Reproduce
Observe the printed event.steps.
```
void initPlatformState() async {
if (!await Permission.activityRecognition.request().isGranted) {
return;
}

_stepCountStream = Pedometer.stepCountStream;
_stepCountStream.listen(onStepCount).onError(onStepCountError);

if (!mounted) return;
}

onStepCount(StepCount event) {
print(event.steps);
sLogic.updateStep(event.steps);
}
```

### Expected behavior
I hope it can also be triggered in the screen_off state. Apps for obtaining step counts generally need to run in the background and be in the screenoff state.

### Actual behavior
What did happen? Include stack traces and exception print-outs.
