refactor: update script execution with sys.executable

Updated the script execution commands to use `sys.executable` instead
of a hard-coded "python" to ensure compatibility with different Python
environments. Additionally, refactored code for better readability
and consistency in formatting, particularly around argument parsing
and error handling in both manage_hetzner_servers.py and
update_local_config.py.

Improves deployment flexibility and code maintainability.
