Use Logger.warning to fix deprecation warnings

[janpieper]

When using commanded with Elixir 1.15, we currently see a lot deprecation warnings for Logger.warn/1:

warning: Logger.warn/1 is deprecated. Use Logger.warning/2 instead                                                                                                                                                   
  lib/commanded/middleware/consistency_guarantee.ex:47: Commanded.Middleware.ConsistencyGuarantee.after_dispatch/1

It should be fine to change Logger.warn/1 to Logger.warning/1 because the new function already exists since Elixir 1.11.

FYI: eventstore already has already been updated to use Logger.warning/1: commanded/eventstore#278

@slashdotdash What about this? 🔽

commanded/mix.exs

elixir: "~> 1.10",

and

commanded/README.md

Line 22 in e20fddd

Requires Erlang/OTP v21.0 and Elixir v1.9 or later.

Can we just increase these to at least 1.11? 🤔

@janpieper Let's bump the minimum Elixir version to v1.11

@slashdotdash Just pushed a new commit with increasing the minimum required elixir version to 1.11 😉
