🌟 Summary

This PR enhances the Ultralytics GitHub action by making the GitHub username and email configurable for commit operations.

📊 Key Changes

• Introduced two new optional inputs: github_username and github_email.
• Set default values for these inputs to "UltralyticsAssistant" and "web@ultralytics.com", respectively.
• Updated the Git configuration step in the action to use these inputs instead of hardcoded values.

🎯 Purpose & Impact

• Customization: Allows users to specify their preferred GitHub username and email for commit descriptions, rather than using the default values.
• Flexibility: Enhances the action's adaptability for different users and workflows, leading to more personalized and descriptive commit histories.
