How to reproduce:

1. Create a new Fresh project.
2. Build the project with deno task build
3. Add vanilla-extract and the vite plugin by running:

deno install --npm @vanilla-extract/css
deno install --npm --dev @vanilla-extract/vite-plugin

4. Add the plugin to your Vite config like this:

import { defineConfig } from "vite";
import { fresh } from "@fresh/plugin-vite";
import { vanillaExtractPlugin } from "@vanilla-extract/vite-plugin";

export default defineConfig({
  plugins: [fresh(), vanillaExtractPlugin()],
});

5. Run deno task build and get an error like the following:

Simple reproduction repo for this issue -> https://github.com/fry69/fresh-vite-vanilla-repro

Just run deno task build to provoke mentioned error.

Seems like an upstream issue. I think they're no accounting for Deno projects where package.json is not a requirement.
