[Issue-3226] JUnit5Xml30StatelessReporter does not change class name in report (#3347)

Fix usePhrasedTestCaseClassName=false still using @DisplayName in XML classname attribute

When phrasedClassName was false, the classname attribute in the XML report incorrectly used sourceText (the @DisplayName value) whenever it was non-null, making the flag effectively a no-op for classes annotated with @DisplayName. The false branch now consistently uses getSourceName(), matching the existing pattern for phrasedMethodName.

On Linux/Unix:

export MAVEN_OPTS="-server -Xmx512m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=384m -XX:+UseG1GC -XX:+UseStringDeduplication -XX:+TieredCompilation -XX:TieredStopAtLevel=1 -XX:SoftRefLRUPolicyMSPerMB=50 -Djava.awt.headless=true"

On Windows:

set MAVEN_OPTS="-server -Xmx256m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=384m -XX:+UseG1GC -XX:+UseStringDeduplication -XX:+TieredCompilation -XX:TieredStopAtLevel=1 -XX:SoftRefLRUPolicyMSPerMB=50 -Djava.awt.headless=true"

In order to build and run the tests:

mvn install site site:stage -P reporting,run-its

To set up the project in Eclipse IDE or IntelliJ IDEA, please follow these steps:
