🌟 Summary

This PR updates the GitHub workflows to enhance security and streamline the token usage in the project.

📊 Key Changes

• Replaced PERSONAL_ACCESS_TOKEN with _GITHUB_TOKEN in multiple workflow files (cla.yml, format.yml, and merge-main-into-prs.yml).
• Updated the token handling for formatting and summarization tasks.

• 🛠 Simplified Configuration: Reduction in the number of secrets needed decreases complexity and potential misconfigurations.
• 📈 Improved Integration: Transition to OpenAI API keys standardizes AI integration, potentially improving consistency and functionality across different projects.
