[nuxt3][vercel] Feature request: Support vercel provider for static app (nuxt generate)

Feature

Feature request: Support (nuxt3) nuxt/image with vercel provider for static app -> nuxt generate.

Expected

Vercel config is generated and contains the “images” property which configures the Image Optimization feature.

Actual

Website is generated, <nuxt-image> components are processed fine, but vercel config does not contain the “images” property.

Reproduction example

Many thanks for the ref @mrdannyjohnson!

I’d guess this work item would mean image variants (srcset) are actually generated + packaged at pre-render (‘generate’) time using e.x. IPX?

Basically I might even prefer this option - but as far as this issue is concerned the Vercel Image Optimization(https://vercel.com/docs/concepts/image-optimization) should be used. Basically the website is static, pre-rendered - but using vercel images, like when running on nitro, SSR…

Example

1. nuxt3 default using nuxt build, nitro, SSR via vercel edge function
   -> https://nuxt3-generate-static-vercel-image-lb046wh8w-info301.vercel.app/)
2. vs. result of nuxt generate
   -> https://nuxt3-generate-static-vercel-image-7scsed04t-info301.vercel.app/

The page in question has only a hand full of routes, as some sort of workaround, I was able to solve what I was trying to achieve by simply configuring all my routes for prerender:

    nitro: {
        prerender: {
            routes: ['/', '/a', '/b', '/c']
        }
    },

It’s deployed to vercel and not served via nitro functions but static as expected. Vercel image provider is still getting configured and working.

ℹ️ I’ll keep the issue open, since I think it would still be good to have vercel image provider working with nuxt generate.
