Section for "contextual components" & google search

I noticed that [somewhere around v3.14](https://github.com/ember-learn/guides-source/search?q=Contextual+Components&unscoped_q=Contextual+Components) the note about "Contextual components" has moved from "Wrapping content in a component" and in v3.19 it lives in section called [Patterns for Components](https://guides.emberjs.com/v3.19.0/in-depth-topics/patterns-for-components/). Which is fine.

But this reveals ~~two~~ a possible problem~~s~~:

Google for whatever reason [points at](https://www.google.com/search?q=contextual+components+ember&oq=contextual+components+ember) article about [block content](https://guides.emberjs.com/release/components/block-content/) and [v3.3.0 of guides](https://guides.emberjs.com/v3.3.0/components/wrapping-content-in-a-component/). Both options are sub-optimal.

~~Even when searching on v3.19 guides via inline Algolia search, I will get no relevant results~~

The content has been there for quite a while, so that does not seem just like a "stale cache" problem. Maybe those are related. Not sure.
