pythongh-111178: Fix PyRangeIter_Type deallocator (python#131162)

vstinner · plashchynski · commit 90a66d5778bd · 2025-03-17T20:50:04.000+03:00
Don't use PyObject_Free() as tp_dealloc to avoid an undefined
behavior. Instead, use the default deallocator which just calls
tp_free which is PyObject_Free().
