Considering refactoring `ManyPydanticModel` to a special case of `PydanticModel`

An obvious generalization would be to make `ManyPydanticModel` a syntactic sugar around `PydanticModel` where the model is 

```python
ManyPydanticModelsAlias = TypeAdapter(list[TModel])
```

This could also provide an interesting way to generalizing parsing using TypeAdapter
