Place Details: Replace field `type` with `types`

[FinnWoelm]

Hi everyone, thanks for the great library :heart:

Just noticed a small bug: According to the Place Details documentation, type is (no longer?) a valid field. Instead, there is now a types field. See: https://developers.google.com/maps/documentation/places/web-service/details#Place-types

This will need to be changed in the list of PLACES_DETAIL_FIELDS_BASIC here: https://github.com/googlemaps/google-maps-services-python/blob/645e07de5a27c4c858b2c0673f0dd6f23ca62d28/googlemaps/places.py#L77
