Normalize CLI Argument Format for Consistency

[felixcarmona]

Summary

This PR introduces a change to the CLI argument format by replacing --hf_token with --hf-token. This adjustment ensures consistency across the tool's interface, as all other parameters follow the hyphenated (-) format rather than using underscores (_). This inconsistency can potentially lead to user confusion and a slight deviation from common CLI practices.

Changes and Impact

• The --hf_token parameter has been updated to --hf-token across the codebase.
• This modification introduces a breaking change, requiring users to adapt their scripts and command-line usage to accommodate the new argument format.
