Code Review
This pull request updates various dependencies for the vertx-web-kotlinx framework, including major version bumps for Kotlin, Vert.x, and Gradle. The changes also involve migrating from epoll to io_uring for native transport. The code has been adapted for breaking changes in the new library versions. My review identifies a critical issue with an unsupported JDK version being configured, which will break the build. I've also noted the use of a release candidate version for Kotlin, which could be a stability risk.

Code Review
This pull request updates several key dependencies, including Kotlin, Vert.x, and Gradle, and introduces a number of performance optimizations. The switch to io_uring, caching of HTTP headers, and fine-tuning of JVM options are all positive changes for a high-performance benchmark. The code has also been updated to align with the new APIs of the updated libraries.
My main feedback is regarding the use of a Release Candidate version for Kotlin and an Early Access version for the JDK. While using cutting-edge versions can be beneficial for testing new features, they can also introduce instability and make benchmark results less reproducible. I've added specific comments on these points.
