Subject: [ruby/rubygems] Cover required_ruby_version and
 required_rubygems_version overrides

Add integration coverage exercising :ignore_upper and nil overrides
against per-gem metadata fields, transitive propagation, and lockfile
re-resolution when a metadata override is added against an existing
lockfile. The cases drive `bundle lock` so they exercise the resolver
without RubyGems' install-time required_ruby_version gate, which is
addressed in a later step.
