prerenderRoutes
prerenderRoutes hints to Nitro to prerender an additional route.
When prerendering, you can hint to Nitro to prerender additional paths, even if their URLs do not show up in the HTML of the generated page.
const route = useRoute()
prerenderRoutes('/')
prerenderRoutes(['/', '/about'])
In the browser, or if called outside prerendering,
prerenderRoutes
will have no effect.
