README: When use require False

[clement1234]

Hello

Since this commit :
0a33e4f

When you realize installation with require: false you will do this to load current_user in audit records.

Installation

Add the gem to your Gemfile:

gem "audited", "~> 5.0"

And if you're using require: false you must add initializers like this:

#./config/initializers/audited.rb
require "audited"

Audited::Railtie.initializers.each(&:run)
