[SPARK-53701] Use Java 25 toolchain while supporting Java 17+
### What changes were proposed in this pull request?
This PR aims to start to use `Java 25 (Azul Zulu JDK)` toolchain while
supporting Java 17+ from `Apache K8s Operator v0.5`.
### Why are the changes needed?
After this PR, we can take advantage of Java 25 compiler improvements while
supporting all Java 17+ versions via `options.release = 17`.
https://github.com/apache/spark-kubernetes-operator/blob/db7e6403fd14ab86c302532423e26d3799a6e4c8/build.gradle#L59
### Does this PR introduce _any_ user-facing change?
- There is no behavior change for users.
- There is no developer experience change in general.
- For the system without Java 25, `Gradle` will automatically download
and use it.
- Since we assume that `Gradle Wrapper` downloads `Gradle` itself, most
of developers should get Java 25 without any issues.
### How was this patch tested?
Pass the CIs.
### Was this patch authored or co-authored using generative AI tooling?
No.
Closes #336 from dongjoon-hyun/SPARK-53701.
