Update dependencies and refactor git integration

- Added new dependencies in `Cargo.lock` and updated `Cargo.toml` to include `gix` for improved git functionality.
- Refactored git-related functions to utilize the `gix` library, enhancing performance and reliability in handling git operations.
- Simplified the process of initializing git repositories and committing changes within the CLI commands.
- Updated tests to reflect changes in git integration and ensure proper functionality.

These changes aim to modernize the git handling in the project and improve overall code quality.
