Change cron job time for infra drift workflow

[mvandenburgh]

From the github actions docs:

The schedule event can be delayed during periods of high loads of GitHub Actions workflow runs. High load times include the start of every hour. If the load is sufficiently high enough, some queued jobs may be dropped. To decrease the chance of delay, schedule your workflow to run at a different time of the hour.

I set it to run the 16th minute of every hour, hopefully that helps.
