Includes the `guzzlehttp/guzzle` package (version ^7.9) in the required dependencies for both the template and the main composer configuration.

This enhances HTTP client capabilities, ensuring compatibility with modern Guzzle versions and strengthening the project's ability to handle HTTP requests.
