[GenAI] Add support for io.opentelemetry.instrumentation:opentelemetry-spring-webflux-5.3:2.28.1-alpha using gpt-5.5 (#8646)
* Scaffold io.opentelemetry.instrumentation:opentelemetry-spring-webflux-5.3:2.28.1-alpha * Dynamic-access coverage for io.opentelemetry.instrumentation.spring.webflux.v5_3.internal.HeaderUtil (1/1) * Native metadata for io.opentelemetry.instrumentation.spring.webflux.v5_3.internal.HeaderUtil * Update generated library support for io.opentelemetry.instrumentation:opentelemetry-spring-webflux-5.3:2.28.1-alpha * Add support for io.opentelemetry.instrumentation:opentelemetry-spring-webflux-5.3:2.28.1-alpha
