Add nkf as a dependency

[y-yagi]

Since Ruby 3.3.0, RubyGems and Bundler warn if users require the gems that will become the bundled gems in the future version of Ruby.
Please see the "Standard library updates" section for the details. https://www.ruby-lang.org/en/news/2023/12/25/ruby-3-3-0-released/

gmo uses nkf. This fixes the following warning.

gmo-payment-ruby/gmo-payment-ruby/lib/gmo.rb:2: warning: nkf was loaded from the standard library, but will no longer be part of the default gems since Ruby 3.4.0. Add nkf to your Gemfile or gemspec.

Sorry to ping you, but do you have a plan to release the new version? This message always shows (e.g. Run rails console) and it's a little bothering.

$ ./bin/rails c
/home/yyagi/.rbenv/versions/3.3.3/lib/ruby/gems/3.3.0/gems/gmo-0.5.6/lib/gmo.rb:2: warning: nkf was loaded from the standard library, but will no longer be part of the default gems since Ruby 3.4.0. Add nkf to your Gemfile or gemspec. Also contact author of gmo-0.5.6 to add nkf into its gemspec.
