refactor(i18n): make components prop required for <Translate>

Rationale: We prefer that people use the `useTranslation` hook instead,
as it has a lower overhead. The only two use cases we're tailoring for
is when you need to use React components as part of the translation resource,
or you are using a non-functional component and thus cannot use hooks.
