fix: use environment variables for MSSQL examples in CI

- Update getExampleConfig() to read DB_USER, DB_PASS, DB_HOST, DB_PORT, DB_NAME from environment variables for MSSQL
- This allows examples to work in CI without requiring config.mssql.php file
- Set environment variables in GitHub Actions workflow for MSSQL examples step
