Update phone_number.py

Correction of the type of variable line_type_intelligence, in response to issue #883

Fixes

The variable line_type_intelligence is typed as an Optional[str], but according to the API documentation, it receives a JSON with the following parameters: mobileCountryCode, mobileNetworkCode, carrierName, type, errorCode. These values must be interpreted and stored in the variable line_type_intelligence, so it must necessarily be a dictionary with a key, a string, and a value, an object. Optional[Dict[str, object]]
