### What changes were proposed in this pull request? This PR updates the builder stage base image of `build-tools/docker/Dockerfile` to `gradle:9.4.1-jdk26-noble`. ```diff -FROM gradle:9.4.1-jdk25-noble AS builder +FROM gradle:9.4.1-jdk26-noble AS builder ``` ### Why are the changes needed? Since SPARK-56088, the project's Gradle Java toolchain is set to `JavaLanguageVersion.of(26)` (`build.gradle`), and all build jobs in `.github/workflows/build_and_test.yml` already run on JDK 26. However, the Docker builder stage still ran Gradle on JDK 25, which forced Gradle to auto-provision JDK 26 inside the container during every image build. Aligning the builder image with JDK 26: - Removes the in-container JDK 26 auto-provisioning step. - Matches the CI build environment for consistent and reproducible image builds. - Reduces external network dependency at build time. The runtime stages (`azul/zulu-openjdk-alpine:26` for `jlink` and `alpine:3.23` for the final image) and the Java 21 bytecode target (`options.release = 21`, `jdeps --multi-release 21`) are unchanged. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Pass the CIs and manually built the Docker image. ``` $ gradle buildDockerImage $ docker run --rm apache/spark-kubernetes-operator:0.9.0-SNAPSHOT java --version ``` ### Was this patch authored or co-authored using generative AI tooling?
