ci: Run stalebot checks multiple times to ensure completion (#27017)

Peter Tripp created

Stalebot has a maximum operations-per-run which is set at 1000. As a
result it may require multiple runs to successfully complete.

This morning it took [three
runs](https://github.com/zed-industries/zed/actions/runs/13921563707/attempts/1)
so set it to run three times two hours apart to avoid hitting github API
limits.
