[Google Scholar API][Documentation] Clarify max value of `num` parameter

[schaferyan]

A customer reached out to ask what the maximum value for num is with the Google Scholar API. They had trouble finding this in our documentation.

While we currently state that num is limited to 20, there might be a way to word this that would make it easier to find. For example, instead of

Parameter defines the maximum number of results to return, limited to 20. (e.g., 10 (default) returns 10 results, 20 returns 20 results).

We could write:

Parameter defines the maximum number of results to return (e.g., 10 (default) returns 10 results, 20 returns 20 results). The maximum value Google Scholar supports for num is 20.
