KAFKA-20168 Downgrade Jetty from 12.0.32 to 12.0.25 to fix SLF4J 2.x
incompatibility (#21559)
Jetty 12.0.30+ introduced SLF4J 2.x fluent API usage
(`Logger.atDebug()`) which causes `NoSuchMethodError` at runtime since
Kafka still uses SLF4J 1.7.x. Downgrade to 12.0.25 which includes the
CVE-2025-5115 fix without the SLF4J 2.x incompatibility.
The issue was discovered and discussed in
https://github.com/apache/kafka/pull/21452#issuecomment-3943544053.
