Mistakes in bottle-song example solution typespecs

[antoine-duchenet]

In the typespecs of .meta/example.ex, the arguments of quantifier/1 and bottle/1 should be non_neg_integer, not the current pos_integer, since it accepts 0 :

defmodule BottleSong do
  ...
  @spec quantifier(non_neg_integer) :: String.t()
  defp quantifier(n), do: Map.get(@quantifiers, n)

  @spec bottle(non_neg_integer) :: String.t()
  defp bottle(1), do: "bottle"
  defp bottle(_), do: "bottles"
end
