Fix 'Close Old Issues' Workflow (#2272)

* Downgrade 'actions/stale' GitHub Action to 'v8' from 'v9.0.0'

This will resolve the issue related to reserving the cache state found in 'v9.0.0' of this GitHub Action, which will make the Workflow process all Issues on every run.. which won't consume a lot of runtime resources by any means, as it's quite an optimized action.

* Increase the 'operations-per-run' from 100 to 150

This will ensure that the GitHub Action 'actions/stale' will not hit the limit of 200 items (an item either a PR or an Issue)
