feat(bevy_app): expose an API to perform updates for a specific sub-app. (#14009)
# Objective

- Fixes https://github.com/bevyengine/bevy/issues/14003

## Solution

- Expose an API to perform updates for a specific sub-app, so we can
avoid mutable borrow the app twice.

## Testing

- I have tested the API by modifying the code in the `many_lights`
example with the following changes:
```rust
impl Plugin for LogVisibleLights {
    fn build(&self, app: &mut App) {
        let Some(render_app) = app.get_sub_app_mut(RenderApp) else {
            return;
        };

        render_app.add_systems(Render, print_visible_light_count.in_set(RenderSet::Prepare));
    }

    fn finish(&self, app: &mut App) {
        app.update_sub_app_by_label(RenderApp);
    }
}
```

---

## Changelog
- add the `update_sub_app_by_label` API to `App` and `SubApps`.
