[Printing-architecture] New issue on GitHub: Bug/Feature/Security selection screen

Hi,

now I have activated the functionality of reporting security bugs 
privately on all repositories of OpenPrinting, but unfortunately, in the 
web UI of GitHub it is not intuitive to find the way to the place for 
reporting a security issue privately.

When I am on your private GitHub, usually on PAPPL, and click the "New 
Issue" button on the Issues page, there appears a selection screen, to 
tell whether my report is about a bug, a feature request, or a security 
bug. The normal GitHub interface is that if I click on "New Issue" I am 
immediately in the form for a public issue report. The private one is 
hidden in the "Security" section ...

Other bug trackers, like good old Bugzilla or Launchpad allow you to 
choose between public and private in the bug input form.

How can I add such a selection page to the GitHub repos of OpenPrinting? 
Or could you add this feature?
