Warning annotations about set-output on each run

[ferki]

The following warnings started to show up in the annotations on each run during

pkgcheck
The set-output command is deprecated and will be disabled soon. Please upgrade to using Environment Files. For more information see: https://github.blog/changelog/2022-10-11-github-actions-deprecating-save-state-and-set-output-commands/

Apparently it happens during the "Set up python" phase of "Run pkgcheck" step.

It seems like to be caused by depending on github:actions/setup-python#v2 while it seems already fixed in v4 of that project.

I'd be happy to send a PR to bump the version of the dependency, but I can't judge the full implications of that change, so I decided to open issue for now.

The issue seems to be fixed in actions/setup-python#517, which became part of their v4 starting from v4.3.0. Also backported to v2 on actions/setup-python#533.

If I understand correctly, the dependencies here are bundled, and described in package.json. Which this means it might be enough to simply regenerate files like package-lock.json and dist/index.js without any actual code changes.

I will try to open a draft pull request about that to gather further feedback.

On October 11, 2022, we annouced plans to deprecate the save-state and set-output workflow commands on May 31, 2023. We have since decided to postpone the removal given the amount of usage we are still seeing with these commands.

Workflows using save-state or set-output in their workflows will continue to work as expected, however, a warning will appear under annotations indicating the planned deprecation. We recommend customers using these commands to upgrade their workflows to use environment files.

So, it doesn't look like the command will be removed any time soon, but finishing this PR will get rid of the warning.
