Add Navigation Menu component

Prerequisites

• This feature already exists in shadcn/ui - if not, it won't be considered here so don't continue with your issue.

Describe the feature

The Navigation Menu is currently missing in the component list, it would be great adding it to the shadcn-svelte

Would be pleased to see this as well. 👍

I believe the dependency this is built on doesn't have that implemented yet.

For now if you want a similar style as the shadcn-svelte page you can reference their source code:
