refactor(use-roadiz-menu): rely on computed url from roadiz skeleton (#610)

The Roadiz skeleton now exposes a server-side computed `url` field via MenuLinkPathNormalizer (linkExternalUrl or internal URL). We can therefore drop the linkExternalUrl fallback and consume item.url directly, which also removes a @ts-expect-error.
