[CI][Integration] Integration test logs may not hide details by group

[kou]

Describe the bug, including details regarding any error messages, version, and platform.

Example:

https://github.com/apache/arrow-java/actions/runs/15243242024/job/42865926806#step:12:2770

Integration: Build: Java
Prepare arguments
Clear output directories and leftovers
Building Arrow Java C Data Interface native library
+ github_actions_group_end
+ set +x
+ mkdir -p /tmp/dist/java
Copying artifacts
+ set +x
+ /arrow/java/ci/scripts/build.sh /arrow/java /build/java /tmp/dist/java
/build/java /
[INFO] Scanning for projects...
...

Because the build script for integration test in apache/arrow also starts group:

arrow/ci/scripts/integration_arrow_build.sh

Lines 56 to 64 in 1943911

	github_actions_group_begin "Integration: Build: Java"
	if [ "${ARCHERY_INTEGRATION_WITH_JAVA}" -gt "0" ]; then
	export ARROW_JAVA_CDATA="ON"
	export JAVA_JNI_CMAKE_ARGS="-DARROW_JAVA_JNI_ENABLE_DEFAULT=OFF -DARROW_JAVA_JNI_ENABLE_C=ON"
	${arrow_dir}/java/ci/scripts/jni_build.sh "${arrow_dir}/java" "${ARROW_HOME}" "${build_dir}/java/" /tmp/dist/java
	${arrow_dir}/java/ci/scripts/build.sh "${arrow_dir}/java" "${build_dir}/java" /tmp/dist/java
	fi
	github_actions_group_end

Grouping log lines https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/workflow-commands-for-github-actions#grouping-log-lines can't be nested.

I'll fix this in apache/arrow not apache/arrow-java.
I'll transfer this to apache/arrow.
