Subject: [PATCH] Make Rack 3 work OOTB

* Rack::Static is not autoloaded anymore
* Headers must be lowercase (not sure where Rack::Lint is coming from)

I prepend `bundle exec` to commands because I end up activating rack 2.2.9 beforehand otherwise.

 If you'd like to contribute you can generate the Rails main branch documentation by running:
 
 ```bash
-rake test:rails
+bundle exec rake test:rails
 ```
 
 You can generate the Ruby default branch documentation by running:
 
 ```bash
-rake test:ruby
+bundle exec rake test:ruby
 ```
 
 The generated documentation will be put into `doc/public` directory.
 To view the just generated documentation start up a rack application by running:
 
 ```bash
-rackup config.ru
+bundle exec rackup config.ru
 ```
 
 Then open http://localhost:9292 in the browser to view the documentation.
