      Support Core Plugin 2.33

      When Jenkins is started, I see the following stack trace in the log:

      Could not attach 'update-center.md' to support bundle

      I first noticed this fairly recently, so I suspect that it was introduced with Support Core Plugin 2.33. I have only seen the message during initial startup.
