Replace `no-response` with `stale` action

[jeffpaul]

Description of the Change

This PR builds on from #245 as the MBilalShafi/no-response-add-label and replaces it with the actions/stale action as the former was still throwing node 12/16 warnings and failing intermittently. The hope in changing to a GitHub first-party action will be improved stability (aka action runs not failing randomly) and proper node version support.
