Less frequent test alerts (#4362)

## Changes
Re-evaluate test alerts every Jan 10 at 09:00, instead of every hour on
every day. Since we clean them up every night, ideally there won't be
any alerts to re-evaluate at that time (or only a few from the new test
runs).

## Why
There was a problem when even deleted alerts are counting towards a
workspace quota. The alerts team is working on that. Another problem is
alerts service hitting compute quotas, which can be due to many
re-evaluations of not yet deleted alerts. This PR addresses the later
problem.
