Fix annotation warnings

[ferki]

This is a proposed PR to fix #9 by updating the bundled version of actions/setup-python#v2.

The changes were generated by running the following commands:

• npm install
• npm run prepare

I am not sure if that's the correct way to do it, or whether it's covering the full scope of changes required or not.

Please review, and provide feedback about whether I'm on the right track or not.

ps.: There are also

3 vulnerabilities (1 moderate, 2 high)

reported by npm install, so it might be a good idea to update more dependencies.

I will try to look into the recommended npm audit and npm audit fix commands, and may push some follow-up commits.

I've pushed a second commit which is the result of running npm audit fix. Let me know if anything else needs updated on top of these changes or even instead of them, and I'm happy update the PR accordingly.

Perhaps some dependencies in package.json?

We have moved to new approach, to use dockerfile variant. So, thank you for the work, but we have better solution for now.
