Link: do not render `<p>`

Issue

Svelte 5 yields a compiler error for <Link> because <div> is an invalid descendent of <p>, which is correct as per W3 spec.

I recommend we align behaviour with Carbon React:

• [ ] When disabled, render an <a aria-disabled="true"> (⚠️ breaking change since <p> has different layout behaviour)

Yes, I think it makes sense to fix this for <v1 if it's blocking Svelte 5 usage.

Fix was released in v0.83.0.
