Update serpapi.py (#4947)
Added link option in _process_response
<!--
In _process_respons "snippet" provided non working links for the case
that "links" had the correct answer. Thus added an elif statement before
snippet
-->
<!-- Remove if not applicable -->
Fixes # (issue)
In _process_response link provided correct answers while the snippet
reply provided non working links
