Configuration of locales for i18n does not work in uPortal 5
Description
The property for configuring locales (portal.properties) is `org.apereo.portal.i18n.LocaleManager.portal_locales`. It's currently not possible to change the default value in the uP5 way.
In uP5, all properties in portal.properties are obligated to accept configuration in uPortal.properties and/or global.properties.
This property currently ignores that method of configuration.
