Replace `no-response` with `stale` action

[jeffpaul]

Description of the Change

This PR replaces the lee-dohm/no-response action with the actions/stale action. I had noticed recently that there were lots of No Response action failures, and after looking into it appears that the former action was no longer supported, throwing node 12/16 warnings, and 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.

I added back the custom EP close message. Note that the updated action waits 3 days to mark an issue as stale and then another 3 days to close. You can configure those timelines in the YML file as well as the related messages for each stale/close comment.
