chore: update cron job frequency to reset github notifications (#8956)

In our [scheduled
runs](https://github.com/dgraph-io/dgraph/actions?query=event%3Aschedule)
we see a number of "ghost" jobs. E.g.
[1](https://github.com/dgraph-io/dgraph/actions/runs/5881148541). This
is probably due to the following sequence of events:
- github actions sends a notification to developer who created /
modified cron job frequency
- if this person is no longer able to receive this notification (i.e. no
longer receiving emails) the action raise this ghost job with an error
about unverified email

This is a bug with github actions. After contacting github support they
suggested changing the cron job frequency in order to reset who receives
the notifications. This may solve the issue.
