No verbosity at all for succesful checks

[niemiaszek]

I tried to setup linting workflow using this action and it obviously works as intended, but it lacks any verbosity, even with --verbose option.

I'd expect successful workflow to output something similar to black formatter action, but there is none. Such example can be seen in this succesful check of mine. Verbosity for failed check exists, but I'd say it's also unsatisfying. Example in this failed check of mine.

Output of checks drastically differs from the one directly ran from isort cli.
