Add CodeQL Analysis to Skunk Application for Enhanced Security and Code Quality

[JavaHammes]

This PR integrates GitHub's CodeQL analysis into the Skunk application repository. CodeQL is a powerful semantic code analysis engine that helps in identifying vulnerabilities and maintaining code quality. By adding CodeQL, we can leverage automated security checks and improve the overall quality of our codebase.

Changes:

• Add CodeQL Workflow:
  • Introduce a GitHub Actions workflow configuration for CodeQL analysis.
  • Configure the workflow to run on pull requests and pushes to the main branch.

Closes #4
