Previously,  converting a Series of timezone-aware pd.NaT to a NumPy array using
.to_numpy("datetime64[ns]") would raise an exception.
It would happen because it could not be converted to datetime64 as a tz-aware value.
This is now fixed by removing the timezone localization from NaT values before the conversion.
