Add Qodana (QA by JetBrains) using GitHub Actions

Watch the video, the last sections show how integrate Qodana with GHA.
Not sure if it's free of use, but might be a good complement/alternative to CodeClimate.

CodeClimate only watches a single branch (in free plan), while Codana might watch all branches.

This is a suggestion, not sure if we want to do it, requires more analysis.
