When subclassing QTranslate in pyside6 and reimplementing the translate method it seems to be possible to return None which pyside6 casts to a null QString.

This behaviour is missing from the type hints.

Current (incorrect) type hint

def translate(self, context: str, sourceText: str, /, disambiguation: str | None = ..., n: int = ...) -> str: ... 

Correct type hint

def translate(self, context: str, sourceText: str, /, disambiguation: str | None = ..., n: int = ...) -> str | None: ... 

This is a companion issue to PYSIDE-3192
