Minimal reproducer for spring-projects/spring-framework#32363

Steps to reproduce

1. ./gradlew build -> fails
2. Go to build.gradle.kts and uncomment the downgrade of spring-web to 6.1.3 here
3. ./gradlew build -> succeeds

Background

As I don't know how I would force HTTP streaming, I created DisableContentCachingFilter to manually invoke ShallowEtagHeaderFilter.disableContentCaching(request);. This is normally done when HTTP streaming is used (see here and here).
