Fix warnings introduced in elixir 1.15

[thomasdziedzic-calmwave]

When upgrading to elixir 1.15, I got a bunch of warnings: warning: Logger.warn/1 is deprecated. Use Logger.warning/2 instead

I think this is because elixir has now switched to the erlang logger in 1.15.

Ah looks like someone already opened a PR to potentially fix this issue: #107
