Set PageType for High Level & Deep Dive Topic pages

Summary

Right now, High Level Topic and Deep Dive Topic pages are set as the "Default Page" Page Type. We need to find a way to set these Page Types (specifically the PageType Data Layer Variable) to be "High Level Topic" and "Deep Dive Topic".

Now that PLANET-7045 is done we can use the "Get Informed" option to set specific DLVs in those pages.

Requirements

• First level children pages of the assigned "Get Informed" page should have pageType: High Level Topic.
• Second level children pages of the assigned "Get Informed
  page should have pageType: Deep Dive Topic.
• These values should applied only when a "Get Informed" page has been assigned.
