[Google Patents API] No `cpc` key is scraped for `organic_results`

[marm123]

One of our users noted that no organic_results return the cpc key. According to our documentation, this is one of the fields that should be returned. We should investigate if we can even scrape this endpoint, and if not, we should update the documentation to not mislead the customers.

CPC doesn't seem to be provided by Google Patents for organic results, even on the patent details pages.

The most likely solution is just to remove these keys in our documentation.

@marm123 @schaferyan CPC is only returned when we set clustered=true in the request, or choose "Classification" in the playground
