single test failure when using rack 3

[Apteryks]

Hello,

In case it's useful, I'm building with rack 3, and there's a single test failure:

starting phase `check'
/tmp/guix-build-ruby-marcel-1.0.2.drv-0/source/test/test_helper.rb:36: warning: assigned but unused variable - extension
/tmp/guix-build-ruby-marcel-1.0.2.drv-0/source/test/mime_type_test.rb:22: warning: assigned but unused variable - content_type
Run options: --seed 37592

Tasks: TOP => default => test

error: in phase 'check': uncaught exception

So it seems there's not much missing!

Thank you!

Thanks @Apteryks.

Updated to only run that test on Rack 2 where Rack::Lint::InputWrapper is rewindable: https://github.com/rails/marcel/commit/ccd4be5043628c4389230b4c012a7115b8e44c81

In Rack 3, Rack::Lint::Wrapper::InputWrapper is not rewindable.
