Webpack + vue.config.js failed to compile

### Reporting a bug?

I've added this to my `vue.config.js`:
```
const path = require('path');
const VueI18nPlugin = require('@intlify/unplugin-vue-i18n/webpack');

module.exports = {
configureWebpack: {
plugins: [
VueI18nPlugin({
include: path.resolve(__dirname, './src/locales/**')
})
],
```

### Expected behavior

`yarn build` should work as before.

### Reproduction

https://github.com/Glandos/unplugin-vue-i18n-issue222
- yarn
- yarn serve

### Issue Package

unplugin-vue-i18n
