Describe the bug (actual behavior)

Hi !

in the new 4.0 release of kafka the inter.broker.protocol.version properties disappeared, and so we end up with the cluster version 1.0-UNKNOWN

This function can't work in 4.0
https://github.com/kafbat/kafka-ui/blob/main/api/src/main/java/io/kafbat/ui/service/ReactiveAdminClient.java#L154

Expected behavior

We expect to have the 4.0 kraft version displayed like before

Your installation details

We used the 1.2.0 image running on Kube

Steps to reproduce

Create a Kraft 4.0 cluster and just connect the UI to it

Steps to reproduce please? A docker compose example would work, here's the one we have for kraft: https://github.com/kafbat/kafka-ui/blob/main/.dev/dev.yaml

Hi,
@Haarolean , can I work on this issue ?

[abhishekray323]

I am able to reproduce issue for this server.properties ; link. But, the dev.yaml mentioned in above comment, doesn't reproduces issue, trying to understand why issue is happening .
