Comment 5 for bug 1588656

I just checked in Click Index to make sure the Highlight translations have been imported there, and they have:

```
curl 'https://search.apps.ubuntu.com/api/v1' -H 'X-Ubuntu-Architecture: armhf' -H 'Accept-Language: zh-CN' | jq -C '._embedded["clickindex:highlight"]'
[
  {
    "_embedded": {
      "clickindex:package": [
        ...
      ]
    },
    "description": "",
    "_links": {
      "self": {
        "href": "https://search.apps.ubuntu.com/api/v1/highlights/app-of-the-week"
      }
    },
    "country_code": null,
    "slug": "app-of-the-week",
    "name": "本周热门"
  },
  {
    "_embedded": {
      "clickindex:package": [
        ...
      ]
    },
    "description": "",
    "_links": {
      "self": {
        "href": "https://search.apps.ubuntu.com/api/v1/highlights/essentials"
      }
    },
    "country_code": null,
    "slug": "essentials",
    "name": "必需品"
  },
  ...
