Steps to reproduce

1. npm install -g @vue/cli@5
2. vue create my-project
3. vue inspect > wp.config
4. Notice that there is no prefetch/preload plugin in the generated webpack config
5. View the prefetch documentation at https://cli.vuejs.org/guide/html-and-static-assets.html#prefetch
6. Notice that it still describes how to use prefetch, following these instructions does not work
7. Clone the repro repo at https://github.com/jmcooper/vue-prefetch-5.0.8, which was generated with the cli (5.0.8) and has had routing and a lazy-loaded route added.
8. Run the project and notice that the lazily-loaded route is not pre-fetched
9. In that project run: npm install @vue/preload-webpack-plugin
10. Add this to the vue.config.js:

configureWebpack: {
    plugins: [
      new PreloadWebpackPlugin(
        {
          rel: 'prefetch',
          include: 'asyncChunks',
        },
      ),
    ],
  },

11. Notice that pre-fetch still is not working

What is expected?

Prefetch should work out-of-the-box or the docs should show how to enable pre-fetch with the webpack config generated by the cli.

What is actually happening?

Prefetch does not work, docs are incorrect, and I can find no way to get prefetch working.
