Elixir 1.15 is deprecating Logger.warn/2 in favor of Logger.warning/2.

It does so since Elixir now relies on Erlang’s :logger, and Erlang uses the term warning instead of warn.

Other terms such as info and error already matched, but warn didn’t. A small change, but I’m glad the log levels now match those of Erlang.
