Add jsonapi-rb support

[SrMouraSilva]

Hello, jsonapi-rb uses

render jsonapi: ...

Instead the configured json or xml

api-pagination/lib/rails/pagination.rb

Lines 11 to 15 in 289716e

	collection = options[:json] || options[:xml]
	collection = _paginate_collection(collection, options)
	options[:json] = collection if options[:json]
	options[:xml] = collection if options[:xml]

My ideia is add a custom parameter that informs possible extensions

# In configuration file
config.render_options = [:json, :jsonapi, :xml]

# In lib/rails/pagination.rb
option = extension(options)

collection = options[option]
collection = _paginate_collection(collection, options)

options[option] = collection

def extension(options)
  for option in config.render_options
    return key if options.key?(key)
  end
end
