Enable limited auto staling for issue reports (#93691)

## About The Pull Request

Change stale action settings so issues with the cleanup flagged or flaky
test report labels will auto close after 28 days. I picked that number
and the specific stale message pretty arbitrarily, so if maints have
better suggestions feel free

## Why It's Good For The Game

Cleanup flagged is supposed to enable auto-staling on an issue but it
was using the wrong setting (stale-issue-label is the setting for what
label to apply to a stale issue, not which issues to stale). As for
flaky bot, there are a ton of these issues built up from years ago that
most likely no longer occur, but nobody knows that so they never get
closed, the old issues are near-useless because GitHub has since deleted
the workflow logs that they occurred in, and if the issue still occurs
then the bot will just open a new report for it
