VitePress does not honor `vite.build.ssr = false`

[Swivelgames]

Describe the bug

Trying to build with vite.build.ssr = false, but it appears that VitePress continues to bundle everything as if preparing it to be served with a backend.

Reproduction

Build VitePress with vite.build.ssr = false

Expected behavior

Paths will become absolute and referenced modules will be bundled with the dist, unless excluded with rollupOptions.external.

I think you're confused between what SSR in this context means. VitePress performs SSR to generate static HTML/JS/CSS. You can host that wherever you want. You don't need a backend to serve that. Regarding paths, you probably need #2467
