There is no issue related to this or I didn't found the one related to this.
This PR fix the "Operations testing" GA that fail on every build ( jest test )
It look like the Core library has made some change on the new version they made ( maybe it's a minor regression ) that make the output::.... no longer appear on the stdout

• Add file commands for save-state and set-output actions/runner#2118
• Add save-state and set-output file commands actions/toolkit#1178

This will impact the slides on the interactions section as well

The PR seems to tell us that the legacy way still works.
I think we should continue to try fixing the test failure rather than hard-code the version.
