Allow turning off warning annotations for no included tests

[uriariel]

It would be helpful to add a flag that would allow turning off warning annotation if there are no failing tests and include_passed is false.

        core.warning(
          `⚠️ No annotations found for ${testResult.checkName}. If you want to include passed results in this table please configure 'include_passed' as 'true'`
        )```

@mikepenz #743 doesn't resolve this issue, I meant adding an option that will allow silencing those alerts even if include_passed is false.

Will lower it to info - #746
Adding an additional config flag which needs to be maintained currently doesn't seem to fit into the action

@mikepenz Thanks!
