test: remove flaky designation for test-cli-node-options

The test failure is not platform-specific and is the result of
manual/human error. Some improvements may be possible, but there is
nothing fundamentally unsound about the test insofar as when it fails in
CI, there is a problem on the host that needs to be addressed and not an
inherent issue with the test.
