This PR removes the workaround that was put in place that allowed a Node16 runtime to be used after its deprecation timeline.

With the merging of https://github.com/redhat-actions/openshift-tools-installer/pull/106, the openshift-tools-installer should now be using a Node20 runtime and the issue that was previously observed (3 minute delay for every execution) is now resolved.
