Workflow for VERSION + CHANGELOG

[Martin-Zeithaml]

I have made #423 to remove obsolete script.

One of checks was complaining on missing VERSION and CHANGELOG.

I have updated the PR description, but the same step is failing again with the same error indicating, that for some reason old PR description is used:
