🌟 Summary

Enhanced git status checks to avoid unnecessary prompts in Docker environments.

📊 Key Changes

• Added a condition to skip git status checks inside Docker containers.

🎯 Purpose & Impact

• Purpose: The change aims to prevent git status warnings from appearing when the YOLOv5 code is being run inside a Docker container. This is because Docker containers are often used for isolated, consistent environments and the software is not expected to be updated within them.
• Impact: Users running YOLOv5 in Docker will have a cleaner console output without irrelevant warnings, resulting in a more streamlined experience.
• It's beneficial for deployment scenarios where the code is not meant to be updated regularly, reducing unnecessary clutter in the logs. 🐳💡
