"cannot load such file -- rack/media_type" on twilio-ruby v5.63.1

[kevin-roe]

Issue Summary

We have a gem (email_search)that wraps twilio-ruby as a part of our internal testing tools. When we ran a bundle update yesterday and installed version 5.63.1, we received the following error upon attempting to execute our tests: cannot load such file -- rack/media_type. I have included the stack trace below. For the fix we hard coded twilio-ruby to use version 5.63.0 which resolved our issue.

Note that this issue doesn't show up in their own testing as their tests explicitly require 'rack' in spec_helper https://github.com/twilio/twilio-ruby/blob/main/spec/spec_helper.rb#L19
