📚 Description

This PR introduces the possibility of conditionally rendered items in UNavigationMenu.

This improves the overall support UNavigationMenu will have to all kinds of navigations, including providing links to items that only need to exist under certain conditions.

For example, only an authorized user should see a link to their profile page.

Not sure about this honestly, it's as easy to filter the items you provide in a computed.

[GalacticHypernova]

Well, true, but I don't see the harm in having it supported natively. You can argue that a lot of features nuxt ui provides can easily be made manually.

Do you foresee any issue with this?
