fix(docker): use JDK instead of JRE for Java UDF compilation (#3628)
## Summary
This PR fixes Java UDF compilation failures in Docker containers by
switching the base image from JRE to JDK.
## Problem
Java UDF operators require runtime compilation of user-provided Java
code using `ToolProvider.getSystemJavaCompiler()`. This compiler is only
available in JDK distributions, not JRE-only images.
Previously, the Docker container used `eclipse-temurin:11-jre-jammy`,
causing compilation to fail with null pointer exceptions.
## Solution
Changed the Docker base image from `eclipse-temurin:11-jre-jammy` to
`eclipse-temurin:11-jdk-jammy` to include the Java compiler tools needed
for runtime compilation.
