Update CI build matrix from Java 24 to Java 25

[simbo1905]

Update the CI build matrix to use Java 21 + Java 25 instead of Java 21 + Java 24.

Files to update:

• .github/workflows/maven.yml (rename test-java24 to test-java25, update java-version)
• .github/workflows/daily-api-tracker.yml (update java-version from 24 to 25)

Java 25 is the latest stable release and should be used for compatibility testing.
