Support edge function caching with netlify-edge preset

[peralta]

Describe the feature

The netlify-edge preset does not honour isr caching settings from Nuxt config. This seems to be intended behaviour and properly documented (https://nuxt.com/docs/guide/concepts/rendering#route-rules), although it would be great to support it for edge functions.

Besides the preset change to add the relevant headers, the generated manifest.json file should set caching to manual.
