Revert "Use self-hosted runner for viable/strict update (#84249)"
This reverts commit acd6ca8cfa9537284928fb5d36834d1e5ae1e6f3.
Reverted https://github.com/pytorch/pytorch/pull/84249 on behalf of https://github.com/malfet due to Broke trunk, as one can't use regular actions on self-hosted runners, see https://github.com/pytorch/pytorch/runs/8092593881?check_suite_focus=true
