Python 3.13 added PyErr_FormatUnraisable(format, ...) which allows logging a specific error message, whereas PyErr_WriteUnraisable() always logs the generic "Exception ignored in ..." message.

I propose to use replace PyErr_WriteUnraisable() with PyErr_FormatUnraisable() to log better (more helpful) error messages.
