Link to Deltares announcement about CoCliCo is broken

[FlorisCalkoen]

When you click on asset in the screenshot below (Deletares catalog level) you'll get a HTTP 404 error because the link no longer exists.

This is the part that in our catalog that contains an old link:

  "assets": {
    "metadata": {
      "href": "https://www.deltares.nl/en/news/development-of-a-new-european-platform-on-climate-services-for-coastal-risks-and-adaptation/",
      "type": "application/html",
      "title": "Deltares Website",
      "description": "Deltares Website about CoCliCo",
      "roles": [
        "metadata"
      ]
    }
  },

Also it might be better to add this as link instead of asset.
