Would be great if we could support the distinctAttribute

Hi @jeremylynch!

Have you tried this?

class Book < ApplicationRecord
  include MeiliSearch::Rails

  meilisearch do
    distinct_attribute [:title]
  end
end

I believe this is not an error since we have this config declared here: lib/meilisearch-rails.rb:55
