Ah except was added in Ruby added except to hashes in Ruby 3.x

https://blog.saeloun.com/2020/09/30/ruby-adds-support-for-hash-except#:~:text=Ruby%20adds%20instance%20method%20%23except,hash%20except%20the%20given%20keys.

Having the min ruby version in the gemspec would have failed better. https://github.com/rubygems/bundler-features/issues/119
