Update swagger version in Ranger

The Ranger website embeds a Swagger UI, AFAICS currently version 2.2.10. Older versions of swagger, such as this one, suffer from a number of security weaknesses.
 
While fortunately https://ranger.apache.org does not have any sensitive cookies or login mechanism or similar, so there isn't really anything to compromise, it would be good to update to a recent version of Swagger. Could you look into that?
 
It is somewhat unclear to me whether the ranger site is maintained in SVN (https://svn.apache.org/viewvc/ranger/site/) or git (https://github.com/apache/ranger-site)
