Eim 281 broadening python support in offline installer

[Hahihula]

on windows we still rely on the python 3.11 as we are installing it ourselves
on POSIX we should now support python versions "3.10", "3.11", "3.12", "3.13"

Summary of Changes

Hello @Hahihula, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly enhances the offline installer's Python support by enabling it to work with a wider range of Python versions (3.10-3.13) on POSIX operating systems. It achieves this by implementing dynamic detection of the Python version during installation and managing version-specific Python wheel packages, ensuring greater compatibility and future-proofing for Python environments.

Highlights

• Broadened Python Support for POSIX: The offline installer now supports Python versions 3.10, 3.11, 3.12, and 3.13 on POSIX systems. Windows continues to rely on Python 3.11.
• Dynamic Python Version Detection: New utility functions have been introduced to detect the Python version within a virtual environment and locate corresponding version-specific wheel directories (e.g., wheels_py311).
• Multi-Version Wheel Downloading: The offline installer builder can now download Python wheels for multiple specified Python versions, creating separate wheel archives for each, which improves flexibility and compatibility.
• New CLI Argument for Wheel Versions: A new command-line argument --wheel-python-versions has been added to the offline installer builder, allowing users to explicitly define which Python versions to download wheels for.

Code Review

This pull request enhances the offline installer by adding support for multiple Python versions on POSIX systems, which is a great improvement for flexibility. The changes include new logic to detect the Python version and locate the corresponding wheel directory. The offline installer builder is also refactored to download wheels for different Python versions.

I've found a couple of areas for improvement: one is a minor code redundancy, and the other is related to robust path handling to prevent potential panics with non-UTF-8 paths. My detailed comments are below.
