Rely on standard `@Repeatable` support in `AnnotationJmxAttributeSource`

[sbrannen]

Overview

AnnotationJmxAttributeSource currently uses RepeatableContainers.of(...) to look up @ManagedOperationParameter and @ManagedNotification as repeatable annotations. However, explicit use of RepeatableContainers.of(...) is not necessary when using the MergedAnnotations API with @Repeatable annotations.
