pymongo filter_fields should default to None, not {}

[spr]

The new filter_fields argument in pymongo changes from None to {}, as with query_filter.

https://github.com/uriyyo/fastapi-pagination/blob/91cdd7a706705d8c5d0dbe51d690fb3db06c4803/fastapi_pagination/ext/pymongo.py#L31

However, in pymongo None means "perform no filtering" and {} means "return only the ObjectId".

So, this results in errors of the following kind:

pydantic_core._pydantic_core.ValidationError: 3 validation errors for Page[Peripheral]
items.0.peripheralID
  Field required [type=missing, input_value={'_id': ObjectId('6286cafb01072e1f8a55b7ca')}, input_type=dict]
    For further information visit https://errors.pydantic.dev/2.5/v/missing

I think this is as simple as removing the linked line to fix the problem.
