Incompatible with @Nested class test

[violetbeach]

In what version(s) of Spring for Apache Kafka are you seeing this issue?
2.7.2 (maybe All)

Describe the bug

when used with @nested, Multiple Contexts appear causing test to break.

Contexts caching miss.

To Reproduce

�this following situations are likely to cause problems.

@EmbeddedKafka
@SpringBootTest
class BeanTwiceTest {

    @Nested
    class NestedClass {
        
        @Test
        void test() {
        }
        
    }
    
}

As a result, errors may occur when using libraries such as WireMock, Restdocs, and contexts may not be reused as intended. (Mockito.verify(instance, times()) fails, etc.)

Expected behavior

Context should appear only once. (Caching must be successful.)

Sample

below is an example of only the test in the Nested Class being broken. (but. After modified)
