Cache does not respect stalePeriod on web

## 🐛 Bug Report

When setting a custom `stalePeriod` on web, the cache remains valid and the browser will access data via the cache rather than sending out a fresh network request, even when the Duration specified in `stalePeriod` has expired.

### Expected behaviour

On all platforms, after a custom `stalePeriod` is set, items should be removed from the cache after the specified Duration has expired.

### Reproduction steps

1. Extend `CacheManager` with a `Config(...stalePeriod: Duration(minutes: 1)`
2. Make a request that uses the CacheManager
3. Wait over one minute
4. Make the same request again

Observe that the second request hits the cache, not the web.

### Configuration

**Version:** 3.3.0

**Platform:**
- [✓] :earth_asia: Web

### Cause

By default, the [config for web uses the NonStoringObjectProvider](https://github.com/Baseflow/flutter_cache_manager/blob/3bd49b866d9b5e6ce09d2283f0ef97488be97e1d/flutter_cache_manager/lib/src/config/_config_web.dart#L19). Old cache objects are removed [using their provider's getOldObjects method](https://github.com/Baseflow/flutter_cache_manager/blob/205387b4c7e4faff5152848b68c98d36e989ec01/flutter_cache_manager/lib/src/cache_store.dart#L143). The implementation of this in the NonStoringObjectProvider [never does anything](https://github.com/Baseflow/flutter_cache_manager/blob/3bd49b866d9b5e6ce09d2283f0ef97488be97e1d/flutter_cache_manager/lib/src/storage/cache_info_repositories/non_storing_object_provider.dart#L38).

Ideally, the web config should be update to use a repo that has a working implementation of `getOldObjects`.

Start with lib/src/config/_config_web.dart and inspect how it selects the storage provider. Then read lib/src/storage/cache_info_repositories/non_storing_object_provider.dart and lib/src/cache_store.dart, focusing on getOldObjects and stalePeriod handling. Reproduce the one-minute web scenario and confirm that an expired item is removed so the next request reaches the network.
