The required_rubygems_version constraint for this specification

A fallback is included because the original version of the specification API didn't include that field, so some marshalled specs in the index have it set to nil.

# File lib/rubygems/resolver/index_specification.rb, line 50
def required_rubygems_version
  spec.required_rubygems_version || Gem::Requirement.default
