Issue:
Logger.warn is deprecated
Compiling on Elixir 1.15.0-rc.1 indicates that some `Logger.warn` calls still need changing or handled gracefully on multiple versions of Elixir. Potential approach   [fyi](https://jeffkreeftmeijer.com/elixir-backwards-compatible-logger/ )
HB version 0.20.0

Pull request description:
Switch to warning/1 with updated build matrix 
This swiitches from `Logger.warn` to `Logger.warning` because `warn` is deprecated, and the upcoming Elixir 1.15 shows a compile-time warning. The `warning` alternative was introduced in Elixir 1.11, so we're officially updating the build matrix to support 1.11 as the minimum Elixir version.

Closes #493
