Link to docs from the UI/component boxes

[andreaskienle]

Description

Where possible, include links from the component boxes to internal documentation that describes each component in detail.

For Landscaper, also provide installation instructions, as this component cannot be installed through our UI.

Challenge

As we do not expose internal links in the public repo, we need to inject the URLs during build time - @n3rdc4ptn / @andreaskienle
