Increase number of operations used by stale

[damccorm]

Right now, our stalebot doesn't process all issues/pull requests. This is because by default, the stale action has a limit of 30 operations per run to avoid rate limiting. Since reading a batch of 100 issues/PRs is considered a single operation, we aren't able to fully make it through the backlog of issues/PRs (which is >4000). This applies even though we are only acting on PRs because GitHub can't effectively tell the difference between the 2.

Upping our limit to 100 will ensure that all pull requests will be processed. Since we only run this once per hour, this shouldn't really impact our rate limit of 1,000 operations per hour for the whole repo's GitHub Actions. We're not utilizing a significant portion of this elsewhere.

Does this mean with the change the number of operation by the workflow is not expected to increase?

No, it will still go up because we need to read ~4,000 issues and ~200 PRs (so at least (4000 + 200)/100=42 operations), plus we will still need to perform write operations (adding labels and closing PRs) sometimes.
