Adjust stalebot to increase operations per run (#20475) 

Up to 3 operations are performed for a newly stale PR (label, message, 
check for closure), with 1 being performed to check to see if a stale PR 
should be closed. This sets the operation limit high enough to capture 
~33 newly stale PRs, which should be more than enough for now.
