🐛 bug(pluralization): inherit pluralization rules ⚠ (#493) by @Raiondesu

Allows pluralization rules to be propagated to children and extended vue components (was only root before).

**Important**: before this fix, child components didn't have any pluralization rules whatsoever. This made custom pluralization only usable on root i18n instances or via $root.$i18n.
