Describe the bug (actual behavior)

Kafka UI doesn't automatically update broker version information is case of broker is updated. It requires kafka ui restart.

Expected behavior

Broker is updated -> kafka ui automatically detects new version.

Your installation details

1. Kafka UI version: ef0dacb v0.6.1
2. No, I run just like a plain jar on EC2, systemd managed.
3. The next command is used to run kafka-ui:
   java -Xmx512M -Xms512M -Dspring.config.additional-location=/opt/config.yaml --add-opens java.rmi/javax.rmi.ssl=ALL-UNNAMED -jar /opt/kafka-ui.jar
   /opt/config.yaml content(only 1 cluster here, we have more, but config is pretty much the same everywhere):

---
kafka:
  clusters:
    - name: CLUSTER_NAME
      bootstrapServers: SERVER_1_URL:9093,SERVER_2_URL:9093,SERVER_3_URL:9093
      readonly: true
      properties:
        security:
          protocol: SASL_PLAINTEXT
        sasl:
          mechanism: SCRAM-SHA-256
          jaas:
            config: 'org.apache.kafka.common.security.scram.ScramLoginModule required username="USERNAME" password="PASSWORD";'
      schemaRegistry: http://SCHEMA_REGISTRY_URL:8081

Steps to reproduce

Setup kafka cluster, non-latest version;
Add it to kafka UI. It will detect cluster's version correctly;
Upgrade kafka cluster;
Check broker version in kafka UI, it will stay the same;
Restart kafka UI, now new broker version will be detected.

Hello @timchenko-a , thank you for raising it
can't say that it is a bug, but its better to update version (and version-related) info from time to time.
will be implemented within #3764
