I am soon going to update rubygem-rack to Rack 3.x+ due to update of Ruby on Rails 8. Here is the PR:

https://src.fedoraproject.org/rpms/rubygem-rack/pull-request/5

But this is going to break rubygem-rack-cors. The test suite fails with errors such as:

~~~
  1) Error:
Rack::Cors#test_0022_should not allow everything if Origin is configured as blank string:
NameError: uninitialized constant Rack::Builder
    test/unit/cors_test.rb:65:in 'load_app'
    test/unit/cors_test.rb:77:in 'block (2 levels) in <top (required)>'
~~~

I would appreciate your help and if this can be fixed prior RoR 8 lands

Reproducible: Always

Actual Results:
Test suite fails testing against Rack 3.x+

Expected Results:
Test suite pass testing against Rack 3.x+
