[Feature request] Do not include stale label while getting stale issues

Hi,

We’re discussing using stale bot in Node.js core repository in https://github.com/nodejs/node/issues/28798

While going through your code, I noticed that the function mark calls getStale for getting stale issues https://github.com/probot/stale/blob/e3c53ebf879cccaf856fba1602fdd67f878c3ee3/lib/stale.js#L42

The function getStale doesn’t exclude already stale issues https://github.com/probot/stale/blob/e3c53ebf879cccaf856fba1602fdd67f878c3ee3/lib/stale.js#L72-L73

The function markIssue marks stale issues as stale https://github.com/probot/stale/blob/e3c53ebf879cccaf856fba1602fdd67f878c3ee3/lib/stale.js#L115-L136

Feature Requests:

1. Do not include staleLabel while searching for stale issues
2. Do not add staleLabel if already present while commenting on stale issues
3. Exclude comment activity from stale bot while unmarking updated issues https://github.com/probot/stale/blob/e3c53ebf879cccaf856fba1602fdd67f878c3ee3/index.js#L41-L43
4. While searching for closableItems in sweep, instead of searching for days since last activity of more than daysUntilClose, search for staleLabel marked for more than daysUntilClose https://github.com/probot/stale/blob/e3c53ebf879cccaf856fba1602fdd67f878c3ee3/lib/stale.js#L49-L63
5. Any other impact this change might have.

This will be helpful in projects where daysUntilClose > daysUntilStale The stale bot will continue commenting every daysUntilStale of activity, and close issues after daysUntilClose
