Keep the `vertx-web-kotlinx` portion updated (#10383)

* Bump all dependencies and toolchains to the latest

* Migrate to Vert.x 5 APIs and bump Kotlin to 2.3.0-RC2 to support Java 25

* Update catching the "connection" reset exceptions

* Try setting `date` with kotlinx-datetime but it doesn't work as expected

Got `java.lang.IllegalStateException: Field offsetHours is not set`.

* Remove the kotlinx-datetime dependency and update the comment

See commit 9cf28f15b6f1806b3ed75260adee8acd822cac91 for a failed attempt to try using kotlinx-datetime.

* Get setting `date` with `kotlinx-datetime` to work

ref: https://github.com/huanshankeji/FrameworkBenchmarks/pull/1

* Review and port some of the changes in `FrameworkBenchmarks/frameworks/Java/vertx/` from commit 057c25b234bae395b1228d6afe0a7fd1c225a74d to commit 1838aa5df242f103a335b74c9095bc88f22643b1, and fix some typos

Some changes are not ported.

There is about 5% performance improvement in the JSON test as tested on my device.

* Increase the io_uring completion queue size to resolve warnings and improve the plaintext test performance

```
io.netty.channel.uring.IoUringIoHandler processCompletionsAndHandleOverflow
vertx: WARNING: CompletionQueue overflow detected, consider increasing size: 4096
```

This is still one warning when the value is set to 8192 as tested on my device, instead of many for the default 4096.

* Benchmark Approach 1 and Approach 3 in `jsonResponseCoHandler` again and fix capitalization BTW

The "Requests/sec" result of Approach 1 is only 40% of Approach 3 as tested on my device.

* Remove an outdated comment as found by Gemini Code Assist

* Use the "connection reset" error code from Netty instead of hard-coding it and also catch Java NIO `SocketException` for developing on other OSs such as macOS and Windows

Tested with the `tfb` command on both macOS and Linux.

* Fix some errors and keep things updated in benchmark_config.json and README.md

 Vert.x-Web in Kotlin with request handling implemented as much with official kotlinx libraries as possible.
 
-Code is written from scratch to be as concise as possible with common code extracted into common (possibly inline) functions. SQL client implementation details and JVM Options are adapted referring to [the vertx-web portion](../../Java/vertx-web) and [the vertx portion](../../Java/vertx). All requests are handled in coroutines and suspend `await`s are used instead of future compositions. Compared to [the vertx-web-kotlin-coroutines portion](../vertx-web-kotlin-coroutines), besides adopting the Kotlinx libraries, this project simplifies the code by using more built-in Coroutine functions and avoids mutability as much as possible. JSON serialization is implemented with kotlinx.serialization and Fortunes with kotlinx.html. The benchmark is run on the latest LTS version of JVM, 21.
