Cron action incorrectly updates commit status of last commit

Initially, the action ran as part of a push to the main branch and passed. Then the cron action ran on scheduled time, failed, but updated the commit status of the commit in the main branch which is incorrect. Cron actions should not update any commit status as they run disassociated from commits, so their results should only be visible in the actions log.
