 This constructor accepts a `Searchkick::Results` as the first argument, plus the usual optional variable hash. It sets the `:items`, `:page` and `:count` pagy variables extracted/calculated out of the `Searchkick::Results` object.

-@results = Model.search('*', page: 2; per_page: 10, ...)
+@results = Model.search('*', page: 2, per_page: 10, ...)
 @pagy    = Pagy.new_from_searchkick(@results, ...)
