Close Old Issues

This script automatically closes issues that have been open for longer than
a specified number of days. It ignores pull requests even if they appear in
the issues list.

Usage:
1. Set your Personal Access Token (PAT) with 'repo' scope permission
2. Configure the repository owner, repository name, and age threshold
3. Run the script: python close_old_issues.py

Requirements:
- requests library: pip install requests
