Update inductor-perf-test-nightly.yml (#95807)
Try to cancel previous commits to avoid wasted runs on older commits. Not sure if a different user's push would cancel an ongoing job.
Currently multiple commits from the same open PR would be running, even though most likely the latest commit's status is of interest.
This tries to see if old workflows could get cancelled.
