Remove redundant -d flag in CI workflow

The -d flag was unnecessarily used in the PHP command within the GitHub Actions workflow for continuous integration. This change simplifies the YAML file by removing the redundant flag, ensuring that the PHP extension is correctly specified without it. This adjustment improves the readability and maintainability of the workflow configuration.
