Fix CallbackData without default Optional (#1370)
* fix: CallbackData set optional as None

* docs: add fix changelog

* Add support for nullable fields in callback data

This update extends the callback data handling by adding support for nullable fields. The code now uses the Python typing structures `Optional` and `Union` to parse such fields correctly. A helper function `_check_field_is_nullable` has been added to assist in efficiently checking if a given field is nullable.
