README, removed applications section

[juanpabloaj]

Maybe modify the application section is not necessary.

I tried this package on elixir 1.14.0 without modify the application section and it works.

I followed this tutorial

The library certainly works without adding it as an application, but what the application does is register the translator.

gen_state_machine/lib/gen_state_machine/application.ex

Lines 1 to 11 in 77776ec

	defmodule GenStateMachine.Application do
	@moduledoc false
	use Application
	@doc false
	def start(_type, _args) do
	Logger.add_translator({GenStateMachine.Translator, :translate})
	Supervisor.start_link([], strategy: :one_for_one)
	end
	end

This is to make it so that GenStateMachine termination messages are properly logged, see https://elixirforum.com/t/why-does-logger-translator-ignore-gen-statem-reports/37418.
