📚 Description

When using nitro route rules, we support client-side handling of redirects with vue-router (as well as nitro on server side). However, there's still an error message printed in the console.

This PR adds a stub component (a bare object) for these routes, so that the error is suppressed.

A bit unrelated, but before I forget it: We should also look into fetching payloads (prerendering + payloadExtraction) when the page has a redirect.

We I think should already skip fetching payloads for redirected paths:

nuxt/packages/nuxt/src/app/composables/payload.ts

Line 89 in ce8a2aa

return !!rules.prerender && !rules.redirect

@danielroe sorry, I meant a redirect via definePageMeta (making it totally unrelated 😂).
