[BUG] DateTimeParseException at JSON.parseObject

### 问题描述

以下代码 fastjson1.x 无问题, fastjson2 在JSON.parseObject报错

### 环境信息

- OS信息： [MacOS 12.7.4 M1 Pro 16 GB]
- JDK信息： [Openjdk 17.0.6]
- 版本信息：[Fastjson2 2.0.51]

### 重现步骤

```java

import cn.hutool.core.bean.BeanUtil;
import com.alibaba.fastjson2.JSON;
import org.junit.jupiter.api.Test;

import java.util.Date;
import java.util.HashMap;
import java.util.Map;

import static org.junit.jupiter.api.Assertions.assertEquals;

public class Issue1711_534 {

@Test
public void testExtraParseMethod() {
Map map = new HashMap();
map.put("now", "00000000");
// Hutool BeanUtil
final MyBean bean = BeanUtil.mapToBean(map, MyBean.class, false, null);

byte[] jsonBytes = JSON.toJSONBytes(bean);
MyBean parsedBean = JSON.parseObject(jsonBytes, MyBean.class);

assertEquals(bean.getNow(), parsedBean.getNow());
}

public static class MyBean {
private Date now;

public Date getNow() {
return now;
}

public void setNow(Date now) {
this.now = now;
}

@Override
public String toString() {
return "MyBean{" +
"now=" + now +
'}';
}
}
}
```

java.time.format.DateTimeParseException: -0001-11-28T00:05:43[Asia/Shanghai]

Start by running the provided JUnit reproducer with Java 17 and fastjson2 2.0.51. Inspect the stack-traced paths in DateUtils.parseZonedDateTime, JSONReader.readMillisFromString, and JSONReader.readDate; done means the MyBean round trip completes without DateTimeParseException and preserves bean.getNow().
