[Google Maps Reviews API] Change default reviews returned from 10 to 8

[alexbarron]

Google Maps is now returning 8 reviews by default in the initial query instead of 10. This was reported by a potential customer and I've reproduced it with a few queries.

I just tested it on around ~60 different businesses and can confirm that the first page always returns 8 results, and the second page returns 10 results if no num parameter is used. It's important to note in the documentation to make sure we don't update it in a way that indicates that every page returns 8 results by default, as it's the case only with the first one.
