Revert "test(config): stop a broken pipe preempting the exit-code diagnosis"

This reverts b772491.

The fix is sound but has nothing to do with workers logs; it landed here to
stabilise this branch's CI. Moved to #6455 off develop so it does not merge or
revert with the workers work. Raised in review on #6410.

Until #6455 lands, the `packages/config` release-script test it stabilises can
flake on a loaded runner.
