Revert "Mute o.e.p.t.DockerTests.test600Interrupt (#91888)" (#91892)

The previous commit introduced a compilation error that did not show up
in CI (because of the test-mute label, I'm assuming). Unblocking main
with a revert for now and will open a separate PR to deal with the
correct AwaitsFix annotation.
