[RUBY] Set referrer limits on google vision api with hocalhost

When I run google vision api in the development environment, I get the error ↓.

'"message"=>Requests from referer <empty> are blocked.' '"status"=>"PERMISSION_DENIED",

Restricting API referrer How to operate even if referrer is restricted in the development environment

If Referer is set in header, it also works with hocalhost.
