fix: bad state error on no argument (#7)

* fix(cli): notify when new version available

- Avoid `Bad state: No element` when no argument passed to the CLI
- Refactor of the code for a cleaner implementation

* fix(cli): add default value to version

Added default value to version on getCurrentVersion to avoid
LateInitializationError when no package found.
