chore: rebuild the dashboard at 04:00 UTC (#36)

The dashboard shows data with one day granularity. New data point is
added by spark-evaluate & spark-stats repositories every midnight
(0:00 UTC).

The current schedule of rebuilding the dashboard at 20:00 UTC meant that
the dashboard was missing the latest data for most of the day.

This commit changes the schedule to run the job at 04:00 UTC. The buffer
of four hours after midnight before running the job should be enough
to accommodate any delays in the pipelines updating daily stats.
