GitAuto: Update pyqt5 to the latest version pyqt6

[gitauto-ai[bot]]

Resolves #25

What is the feature

Upgrade the project from PyQt5 to PyQt6.

Why we need the feature

PyQt6 offers improved performance, better support for the latest Qt features, and ongoing maintenance and updates. Upgrading ensures compatibility with newer Qt versions and takes advantage of the latest enhancements and security fixes.

How to implement and why

1. Update Dependencies: Modify the requirements.txt file to replace PyQt5 with PyQt6.
2. Update Import Statements: Go through the codebase and update all import statements from PyQt5 to PyQt6.
3. Modify Code for Compatibility: Address any breaking changes between PyQt5 and PyQt6, such as changes in module names, deprecated methods, or altered APIs.
4. Update UI Files: If the project uses Qt Designer .ui files, ensure they are compatible with PyQt6 or regenerate them if necessary.
5. Testing: Rigorously test the application to identify and fix any issues that arise from the upgrade.

This step-by-step approach ensures a smooth transition by systematically addressing dependency changes and code compatibility.

About backward compatibility

This upgrade will not maintain backward compatibility with PyQt5. All project dependencies and code will be updated to exclusively support PyQt6, leveraging its latest features and improvements. Users will need to install PyQt6 to run the updated application.
