Feature Request: Redirect config for external links

[tugrulates]

Currently, Deno Deploy does not have a redirect config (like Netlify _redirects, or vercel.json files).

It would be nice if this adapter takes in a config for permanent or temporary external redirects, and handles them. Astro can only handle internal redirects.

This would help with SEO, and user experience when redirecting from naked to domain to www, or redirecting from typo domains etc.

The only workaround (short of rewriting the built-in server) I could find so far is to create a second project in Deno Deploy with a simple redirect.
