[DuckDuckGo API] Change start parameter description

[marm123]

It looks like the start parameter for DuckDuckGo API is misleading. Currently it states that the first page returns between 26 and 30 organic_results, and all the subsequent calls with the start parameter return 50 organic_results.

I tested against a couple of different search queries, and start values, and it looks like the initial API call always returns 10 organic_results, and any subsequent API calls with the start parameter (any value) returns 15 organic_results

Current state:

Potential change:

Playground - initial request: 1st example | 2nd example | 3rd example
Playground - with start parameter: 1st example (start=2) | 2nd example (start=10) | 3rd example (start=40)
