Get us better debugging output for new Github Stale Action

[uberbrady]

I've been working on re-activating a "Stalebot" functionality for our GH issues. But I haven't gotten any descent output yet. I suspect this is because our GH issues are all pretty lively - at least, the ones near the 'front'. So this increases the number of issues we look at, and also starts looking from the beginning rather than the end - which, hopefully, should get us some useful debugging output we can use to dial in a configuration that works for us.

PR Summary

• Changing stale action configuration
  The setting that controls the order in which items are processed has been updated to prioritize older items.

• Increasing operations per run
  The number of operations the program can perform in a single run has been increased. This is likely to lead to a marked improvement in performance during debugging stages.
