Add CodeQL analysis workflow configuration

[prokopis3]

This pull request adds a new GitHub Actions workflow for CodeQL analysis to the repository. The workflow is designed to automatically scan code for vulnerabilities and errors in both pull requests and scheduled runs, supporting multiple languages (specifically actions and python in the initial configuration). This enhances the project's security posture by integrating automated code scanning.

Security and Code Quality Automation:

• Added .github/workflows/codeql.yml to enable CodeQL scanning for actions and python code, running on pushes, pull requests, and a weekly schedule.
• Configured the workflow to use appropriate runners based on language, set up permissions, and allow for easy extension to additional languages or custom queries.
