[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_

从堆栈跟踪第 51 行确定的 org.apache.servicecomb.swagger.extend.introspector.JsonPropertyIntrospector.findPropertyDescription 开始。通过 SwaggerUtils.resolveTypeSchemas 对 ClassRsp 和 RecordRsp 运行提供的 MainTest 复现，然后验证包含 Lang 的 record 属性不再引发 NullPointerException，同时现有的 Class 情况仍然成功。
