Increase io.netty.iouring.ringSize for some Vert.x benchmarks that use io_uring (#10384)

I see the following warnings when running these benchmarks on my device:
```
io.netty.channel.uring.IoUringIoHandler processCompletionsAndHandleOverflow
vertx: WARNING: CompletionQueue overflow detected, consider increasing size: 4096
```
