[BUG] - JsonPropertyIntrospector处理record类型里的枚举值时，会报空指针异常

### Steps to Reproduce

简单示例：
```java
package test;

import io.swagger.v3.oas.annotations.media.Schema;
import io.swagger.v3.oas.models.OpenAPI;

import org.apache.servicecomb.swagger.SwaggerUtils;
import org.junit.jupiter.api.Test;

class MainTest {
@Test
void test() {
SwaggerUtils.resolveTypeSchemas(new OpenAPI(), ClassRsp.class); // OK
SwaggerUtils.resolveTypeSchemas(new OpenAPI(), RecordRsp.class); // ERROR
}

public enum Lang {
JAVA, CHINESE, UNKNOWN;
}

public static class ClassRsp {
@Schema(description = "language")
private Lang lang;

public Lang getLang() {
return lang;
}

public void setLang(Lang lang) {
this.lang = lang;
}
}

public record RecordRsp(
@Schema(description = "language") Lang lang
) {}
}
```

### Expected Behavior

报错：
```
java.lang.NullPointerException: Cannot invoke "java.lang.reflect.AnnotatedElement.getAnnotations()" because the return value of "com.fasterxml.jackson.databind.introspect.Annotated.getAnnotated()" is null

### Additional Context

_No response_

Inizia da org.apache.servicecomb.swagger.extend.introspector.JsonPropertyIntrospector.findPropertyDescription, identificato alla riga 51 dello stack trace. Esegui la riproduzione MainTest fornita tramite SwaggerUtils.resolveTypeSchemas sia per ClassRsp sia per RecordRsp, quindi verifica che le proprietà di record contenenti Lang non generino più una NullPointerException, mentre il caso Class esistente continui a funzionare correttamente.
