SG-40980 Add support for VFX CY2026 - Python 3.13 - Qt 6.8

[julien-lang]

This pull request updates support for newer Python and VFX Reference Platform versions, improves compatibility with Python 3.13, and includes several bug fixes and documentation updates. The most significant changes are compatibility improvements for Python 3.13, updates to documentation and badges, and minor bug fixes and refactoring in the vendored shotgun_api3 library.

Python 3.13 and VFX Platform Support

• Updated badges in README.md to reflect support for VFX Reference Platform CY2022–CY2026 and Python 3.9, 3.10, 3.11, and 3.13.
• Updated CI pipeline to use a branch that supports Python 3.13 (azure-pipelines.yml).

Python Compatibility and Bug Fixes

• Added shims in pyside6_patcher.py to prevent warnings for exec_ methods, improving PySide2/6 compatibility.
• Adjusted test logic in test_sgre.py to handle deprecation of positional arguments in Python 3.13.
• Fixed file URL handling in test_shotgun.py to be cross-platform and clarified usage of keyword arguments for download_url. [1] [2]
• Updated a warning message to recommend upgrading to Python 3.13 instead of 3.11.

Vendored shotgun_api3 Updates

• Bumped vendored API version to 3.10.0 and updated commit ID. [1] [2]
• Improved docstring formatting and links for the export_page method.
• Refactored authenticate_human_user to use a finally block for restoring config, simplifying error handling.
• Simplified datetime parsing in _inbound_visitor to use datetime.datetime.strptime.
• Fixed typo in a comment and removed an outdated Python 2/3 compatibility note in shotgun.py. [1] [2]

General Improvements

• Minor code cleanup (removed extra blank line) and added missing imports for clarity in test files. [1] [2] [3]
