Bug 1790476 - Add a cron to run browsertime tests weekly on the mozilla-release branch. r=sparky,perftest-reviewers

This patch limits the frequency of performance tests running on the mozilla-release branch. In particular, we need to reduce the load on our android devices for the time being, similar to how we did this for the beta branch in bug 1788026.
