The PR changes in .github/workflows/gradle.yml replace Java 21 with Java 25 in the buildGradle, mongodbFunctional, and hibernate5Functional job matrices, rather than adding Java 25 alongside Java 21. This matches your observation that the description should be updated to clarify the removal of Java 21 testing in those matrices, or Java 21 should be retained if the change was unintentional.
