Added debugging GitHub Action

[lslezak]

Problem

• The automatic submission to OBS is sometimes skipped.
• Example run
• For some reason the condition to start the action is not evaluated to true.
• But because the condition is not trivial and involves JSON parsing it is hard find the reason why the action was skipped.

Solution

• Added a debugging action which prints the details of the autosubmission configuration and the final result.
• Example run
• It takes just few seconds and it should never fail so it should not block development or merging pul requests.
• The action should be removed when we find and fix the problem.
