Link should support relative href in dynamic routes

Feature request

The problem is that for Links inside a particular dynamic route like “/site/[slug]/comments” you have to always use the additional as prop and somehow grab the slug variable.

Describe the solution you’d like

It should be possible to use relative hrefs inside dynamic routes. For example we are on some page /site/123 And we want to provide a Link to the comments /site/123/comments. Instead of writing

<Link href="/site/[slug]/comments" as={`/site/${slug}/comments`}>
  <a>Comments</a>
</Link>

We should be able to tell the router, that comments is a relative path of the current page. For example:

<Link href="./comments">
  <a>Comments</a>
</Link>
