docs: // displayUnencryptedWarning warns the user when using an insecure credential storage.
  // After a deprecation period, user will get prompted if stdin and stderr are a terminal.
  // Otherwise, we'll assume they want it (sadly), because people may have been scripting
  // insecure logins and we don't want to break them. Maybe they'll see the warning in their
  // logs and fix things.
