Fix #15156: Enhancement: Add support for move-assignment for operatorEqToSelf - #8977

The current running Python version 3.10.12 is older than 3.14. It works fine with aqtinstall in most cases, but may have bugs with file type detection. If you are experiencing errors related to "zipfile.BadZipFile", please upgrade Python. For details, please see upstream report: https://github.com/miurahr/aqtinstall/issues/1042
