RubyZip 3.0 Upgrade

[wheatley]

Need to check that we're not using any of these:

RubyZip 3.0 is coming!

---

The public API of some Rubyzip classes has been modernized to use named
parameters for optional arguments. Please check your usage of the
following classes:

• Zip::File
• Zip::Entry
• Zip::InputStream
• Zip::OutputStream

Please ensure that your Gemfiles and .gemspecs are suitably restrictive
to avoid an unexpected breakage when 3.0 is released (e.g. ~> 2.3.0).
See https://github.com/rubyzip/rubyzip for details. The Changelog also
lists other enhancements and bugfixes that have been implemented since
version 2.3.0.

It's unclear to me what's changing here. Locking gemfile to 2.3.0 seems the simplest.
