REST API information is "hidden" under the REST button

Problem Definition

The 5.12.1 REST API information on this page is "hidden" under the "REST" button, while the page itself remains practically empty.

Suggested Solution

Reformat the page, so it looks similar to its 4.14.5 equivalent

Why this is important

The current layout may be confusing to the users that are accustomed to the previous layout.
