Invalid match statement in DynamicSchemaService#property_locale

[aploshay]

DynamicSchemaService#property_locale currently has:

      return property.to_s.capitalize unless locale_key.match('label' || 'help_text')

which only matches on the 'label' value, whereas

      return property.to_s.capitalize unless locale_key.match(/(label|help_text)/)

matches on either value, as intended.
