Resolves part of #34337

Actually I need also to add:

```
"languages": {
    "Vue.js": {
      "language_servers": [
        "vue-language-server",
        "emmet-language-server",
        "..."
      ]
    }
  },
```

not sure how to resolve fully, happy to continue only little guidance
needed.

Release Notes:

- allow emmet in Vue.js files
