What happened?

The CLI displays a spinner in some places, but this will fail with an error if a TTY is not present. We fixed this in one place in https://github.com/buildkite/cli/pull/409, but there are many other places where the standard spinner.New() is still being called. We should replace all those with SpinWhile, or perhaps consider discarding the spinner entirely. At any rate, there shouldn't be a hard requirement on a TTY.
