Changes proposed in this pull request:

• Adds a type hint for ImageFile.LOAD_TRUNCATED_IMAGES.

  Sets the type to bool, otherwise Literal[False] is assumed causing a lint error when setting ImageFile.LOAD_TRUNCATED_IMAGES = True.

Hi. What environment were you in when you saw the error? Believe it or not, here's what I already see with Pillow 12.0.0 in PyCharm.

Hi! Ah this will teach me for trying out new toys haha. I'm using ty in VS Code. It's interesting it's picked up as a Literal, it seems stricter than other type checkers.

Forgot to include in the original message but also using pillow===12.0.0.

Thanks. I can verify that your fix does satisfy ty.

While the change you've suggested here is minor, I expect there will be other ty problems lurking. I'm somewhat hesitant about trying to satisfy multiple type checkers at once, particularly when ty is still in beta.

Mypy is pretty slow, it would be good to move to a new fast one such as ty or pyrefly at some point. But I've not really looked into them, and with default settings report over 300 and 600 errors each...
