refactor: improve Anon installation script for terms acceptance

- Updated the installation process to rely on debconf preseed and file-based acceptance methods, reducing the need for interactive prompts.
- Limited the number of "yes" responses piped during installation to enhance reliability and prevent infinite loops.
- Streamlined the command execution for fetching and running the installation script from GitHub.
