vite 6 breaks deno support when `npm:` specifer is used in config file

[kazushisan]

Describe the bug

Vite fails to run on Deno after upgrading to v6 when the config file includes an import statement with the npm: specifier.

I think I have a solution so I'd like to work on a patch!

Reproduction

https://github.com/kazushisan/vite-v6-deno-bug

Steps to reproduce

using the following config:

import { defineConfig } from 'npm:vite@6'
import react from 'npm:@vitejs/plugin-react'

// @deno-types="npm:@types/react@18.3.3"
import 'npm:react@18.3.1';
// @deno-types="npm:@types/react-dom@18.3.0"
import 'npm:react-dom@18.3.1'

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [react()],
})

execute the following command:

deno run -A --node-modules-dir npm:vite@5 dev

will work as expected, however the if I change the version to v6, vite will throw an error.

deno run -A --node-modules-dir npm:vite@6 dev

TypeError: [ERR_UNSUPPORTED_ESM_URL_SCHEME] Only file and data URLs are supported by the default ESM loader.
