Add support for the `GitHub` output format

[Danil42Russia]

Is your feature request related to a problem? Please describe.
You cannot upload a Sarif report to private repositories.

If you are on a GitHub Free or GitHub Pro plan, you can only use code scanning on repositories that are publicly available.

Describe the solution you'd like
Add support for output format via Workflow commands for GitHub Actions

https://docs.github.com/en/actions/reference/workflows-and-actions/workflow-commands

Additional context
A rather useful feature that allows you to spot an error in Files changed without opening the GitHub Actions job logs.

Sarif does not work in private repositories (as I mentioned in the task), so that errors are visible during review, I suggest adding output in the format Workflow commands for GitHub Actions.

Oops, only skimmed. I have no interest in doing this, just as I have no interest in sarif, I might accept a PR, but I kind of don't want yet another way to output results, it seems to me much better to out this in your own action that can parse either the sarif or json output instead, but that's just an idea.
