Investigate broken pre-rendering due to I18N

Had to disable auxilliary pages pre-rendering in nuxt.config.ts due to issues with build.

```
 ERROR  [request error] [unhandled] [GET] http://localhost/_i18n/6Uir1KyR/en/messages.json
 Nuxt I18n server context has not been set up yet.
```

Should be re-enabled eventually.

Might be fixed in nuxt/i18n v10 which will be delivered in Nuxt Ignis v0.6.0 🤔
