Demonstrate taxonomies

[JanLenoch]

Blocked: kontent-ai/gatsby-packages#1

Motivation

Kentico Cloud has two artifacts to support categorization of content: Taxonomy elements and Multiple choice elements. The difference is in the scope: While taxonomies are project-wide, multiple choice elements are content type-only.

We don't have any taxonomy elements in the sample Portfolio project yet.

Proposed solution

If you're interested in implementing the story, drop a comment to this issue and you'll be given edit permissions to the project in Kentico Cloud. You'll be able to create a taxonomy of your choice and use it in a Taxonomy element in one of the content types. Then, you'll be able to implement the story in the starter.
