fix: fix the signature error when using reflection to access the org.…

…springframework.core.annotation.AnnotatedElementUtils#getMergedAnnotation method

Fix the problem,the method
org.apache.dubbo.config.spring.util.AnnotationUtils#tryGetMergedAnnotation
utilizes reflection to access
org.springframework.core.annotation.AnnotatedElementUtils#getMergedAnnotation.
However, there is a signature mismatch in the method's input parameters,
which leads to an inability to retrieve the correct method.
Consequently, this results in the failure to obtain the
mergedAnnotation.
