[bug]: custom_ranking in Algolia::Search::SearchParamsObject causes error

[nedski]

Description

Including custom_ranking array in Algolia::Search::SearchParamsObject causes error.

example:

results = client.search_single_index(
  index_name,
  Algolia::Search::SearchParamsObject.new(query: "diabetes", 
                                          length: matches_to_return, # number of results to return
                                          hits_per_page: matches_to_return, 
                                          custom_ranking: ["desc(pubYear)"],
                                          offset: 1, # appears to be one-indexed 
                                          get_ranking_info: true,
                                          attributes_to_retrieve: ['title', 'description']
                                    )
)

This appears to be a bug with the Algolia API, not the Ruby library. Requests via curl with a customRanking attribute fail with a 400 error.
