fix(dev-infra): delay checking if a closed pr has been merged by 30 seconds (#40181) 

Delaying the check if a closed PR was closed by a merge or just closed by 30 seconds
allows for Github to have time to update the PR to be associated to the commit which
closed the PR.  Without this delay, a race condition can exist in which we check for
how a PR was closed before this association is made.
