Move rubocop directive inside Validates module

The rubocop:disable comment placed before `module Minfraud` was being
interpreted by YARD as documentation text, causing "rubocop:disable
Metrics/ModuleLength" to appear on the Minfraud.html documentation page.

Moving the directive inside the module (as part of the Validates module
documentation block) prevents YARD from picking it up while still
applying to the correct scope.
