[SPARK-55374] Remove `vendor` requirement from Java toolchain
### What changes were proposed in this pull request?
This PR aims to remove `vendor` requirement from Java toolchain.
### Why are the changes needed?
To be robust in CIs by allowing all Java 25 vendors.
Previously, we use `Azul` in CI and Dockerfile like Apache Spark main
repository. However, **Gradle docker image uses `Temurin`**. This mismatch
causes the flakiness in CIs.
