Support wrapper class in BooleanGetMethodName rule (#5253)

- Updated XPath rule to include both  primitive and  wrapper class:
                  (PrimitiveType[@Kind = 'boolean'] or ClassType[pmd-java:typeIs('java.lang.Boolean')])
                - Added test cases to ensure that methods returning  are also flagged correctly.
                - Ensured the rule enforces consistent method naming for both primitive and wrapper types.
