Update README.md with accurate Python project description and setup instructions

[Copilot]

Changes

Updated the README.md file to accurately reflect the repository's content and purpose. The previous README contained incorrect setup instructions that referenced npm install, despite the repository containing only Python scripts with no Node.js dependencies.

What Changed

• Project Description: Clarified that this is a test repository for exploring GitHub Copilot features and Python development
• Setup Instructions: Replaced incorrect npm-based instructions with proper Python setup requirements
• Usage Section: Added detailed usage instructions for both Python scripts:
  • hello.py - Simple Hello World demonstration
  • sort_descending.py - Interactive number sorting with example input/output
• Repository Contents: Added a clear inventory of files and their purposes
• Contribution Guidelines: Enhanced with clearer steps and proper bash syntax highlighting
• License: Added a note about the educational/experimental nature of the repository

Example Usage

The README now includes practical examples like:

python3 sort_descending.py
# Input: 5 2 8 1 9
# Output: Numbers in descending order: [9, 8, 5, 2, 1]

All scripts have been tested to verify they work as documented in the README.

Fixes the issue by providing a complete, accurate, and well-formatted README.md file that properly describes the test repository and its Python-based content.
