Regression: #229 on Ruby 3.3

Hey folks, this seems to have caused a regression whereby https://github.com/Data-Liberation-Front/csvlint.rb/issues/229 resurfaces when using the gem standalone on Ruby 3.3. I hotfixed it by adding require 'active_support/all', but I don't know how good a fix that is.

I reproduced the issue and the mentioned fix works. Let me see if I can add a test to catch that error.

It does works on older Ruby versions.

Ruby 3.3.5
