Ruby 3.0 support

[benone]

For ruby 3.0 support:
https://www.ruby-lang.org/en/news/2019/12/12/separation-of-positional-and-keyword-arguments-in-ruby-3-0/

Params to I18n should be passed this way:

  def translate(key, options = {})
    I18n.translate(key,   **options.merge({ :locale => LOCALE }))
  end        
  
  def localize(object, options = {})
    I18n.localize(object, **options.merge({ :locale => LOCALE }))
  end

This problem in _custom_error_message.rb:45:in full_messages too
I18n.t(:"errors.format", options.merge(:message => m))
must be changed to
I18n.t(:"errors.format", **options.merge(message: m)
It is deprecated but works
