[Ruby][FlightSQL] Arrow::Flight::CallOptions isn't used for auto prepared statement close request

[kou]

Describe the enhancement requested

options = ArrowFlight::CallOptions.new
sql_client.prepare("... SQL ...", options) do |statement|
  # ...
  # statement.close is called automatically without the "options" but
  # the "options" is used like statement.close(options).
end
