CI: do not hide error logs in a group

This PR avoids creating a GHA group at the very end of a CI workflow when some failure has happened. Before, when a failure has happened, its GHA group was not closed, however the clock drift check function would create a new group, which would actually close the group containing the error log, thus making errors hidden by default, which is not ideal.
