Shorten the PR staleness from 6 months to 3 weeks + 1 week notice. PRs become much harder to deal with the old they become due to merge conflicts and divergence.
Updated to stale@v7.0.0
The default operations per run is 30 which would be consumed on the reprocessing already-marked issues. Greatly increased the operations per run to process all issues and pull request (~200 + 83 * 5).
Uses the Stale action (https://github.com/actions/stale) to help clean up older Issues and PR. Set to 6 months to mark as stale, and 14 days to close stale.
