Bug 1705639 - bump max run time for periodic-update job. r=RyanVM,releng-reviewers,jmaher DONTBUILD

Updating the HSTS preload list is now taking close to the previous limit
of 5 hours, so bump it to 6 hours as a stopgap, and adjust the start
time to keep its end time from going too late in the day.
