SSR should provide ESM version

[lzxb]

I use Rspack to build the client and server separately

client

This is right
server
This is wrong

I can only obtain the correct export when I set up the client's ESM version on the server side

      config.resolve!.alias = {
          ...config.resolve!.alias!,
          vue$: 'vue/dist/vue.runtime.esm-browser.js'
      };

When I implement an ESM SSR program without setting external dependencies on Vue, it will result in errors in the packaged files.
