ci(github): Migrate from GitLab CI and update deprecated actions

This commit finalizes the migration from GitLab CI to GitHub Actions as the primary CI/CD platform for the project.

The `.gitlab-ci.yml` file has been removed.

The GitHub Actions workflow has been updated to resolve deprecation errors. The following actions have been upgraded to their latest stable versions:
- actions/checkout@v3 -> v4
- actions/upload-artifact@v3 -> v4
- actions/download-artifact@v3 -> v4
- github/codeql-action/upload-sarif@v2 -> v3
