Subject: [PATCH] workflows/premerge: Move concurrency definition to workflow
 level (#126308)

Prior workflow runs were not being cancelled when the pull request was
closed, and I think this was why. Also, there is no advantage to having
the definitions at the job level.

(cherry picked from commit 6e5988863177e1d53e7a7abb7a3db2b85376f0f5)
