[Open data] Remove internal links in Build-OpenData for resource types

[flanakin]

⚠️ Problem

Updating the resource types dataset brings in some internal testing links. Those should not be included in the dataset.

🛠️ Solution

Filter the following links out of the final dataset:

[
  { "title": "Get consistent", "uri": "https://aka.ms/portalfx/designpatterns" },
  { "title": "Learn more", "uri": "https://aka.ms/portalfx/browse" }
]
