[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_

Beginne bei org.apache.servicecomb.swagger.extend.introspector.JsonPropertyIntrospector.findPropertyDescription, das in Zeile 51 des Stack Traces identifiziert wurde. Führe die bereitgestellte MainTest-Reproduktion für sowohl ClassRsp als auch RecordRsp über SwaggerUtils.resolveTypeSchemas aus und überprüfe anschließend, dass Record-Eigenschaften, die Lang enthalten, keine NullPointerException mehr auslösen, während der bestehende Class-Fall weiterhin erfolgreich ist.
