Changes the schedule so that both actions run every day at 12:00 UTC …

…(5AM PST & 8AM EST) (#1576)

This is a better schedule because it runs right before people start working in our team
hence giving us a chance to quickly respond to failures, also doesn't take the computing capacity
when we need it (during working hours). Finally this will capture more changes than before because
there's a chance the code gets updated after hours.
