[Hive v4] Type mistmatch when get List<T> items.

```
//register
Hive.registerAdapter('SampleModel', (json) => SampleModel.fromJson(json));

//open box
final box = Hive.box>(name: 'myBox');

//add items to specific key
box.put('list', const [SampleModel(id: 1, name: 'name'), SampleModel(id: 2, name: 'same')]);

//get items
final list = box.get('list');
```

When I try to get items from key fromJson method throws exception like "Type mismatch. Expected List but got List". Message comes from type_registry.dart class inside of the fromJson method.

If I add register adapter for list type like this

```
Hive.registerAdapter>('List', (json) {
if (json is List) {
return json.map((e) => SampleModel.fromJson(e)).toList();
}

debugPrint('json type: ${json.runtimeType}');
return [];
});
```

then exception message change "Type mismatch. Map but got List".

Exception throws because fromJson method doesn't support list type.

For solution we can check json is List.

Start in type_registry.dart and inspect the fromJson method, then reproduce the issue with the provided Hive.box> example and adapter registration. Done means retrieving the stored list no longer raises a type-mismatch exception for List.
