[BUG]嵌套解析字段值不能是数值

### 问题描述
*简要描述您碰到的问题。*

### 环境信息
*请填写以下信息：*

- OS信息： win10
- JDK信息： 1.8
- 版本信息：Fastjson2 2.0.53

### 重现步骤
*如何操作可以重现该问题：*

1. 使用 `main` 方法
2. 当 `condition: 100` 时报错，`condition: "100"`正常，即condition 不能是数值
3. 出现 `...` 错误
```java
public class fastjson {

public static void main(String[] args) {
String json1 = "{ \n" +
" \"key\": \"1721210291174\",\n" +
" \"type\": \"PARALLEL\",\n" +
" \"action\": [],\n" +
" \"priority\": 1,\n" +
" \"condition\": [\n" +
" {\n" +
" \"key\": 1704359623221,\n" +
" \"type\": \"AND\",\n" +
" \"action\": [{\"operator\": \"ASSIGNMENT\", \"leftOperand\": \"@@89\", \"rightOperand\": 128}],\n" +
" \"priority\": 1,\n" +
" \"condition\": [\n" +

" { \"type\": \"LEAF\", \"action\": [], \"priority\": 3, \"condition\": 100 }\n" +
" ]\n" +
" },\n" +
" {\n" +
" \"key\": 1704359623221,\n" +
" \"type\": \"LEAF\",\n" +
" \"action\": [{\"operator\": \"ASSIGNMENT\", \"leftOperand\": \"@@89\", \"rightOperand\": 328}, {\"operator\": \"ASSIGNMENT\", \"leftOperand\": \"@@89\", \"rightOperand\": 428}],\n" +
" \"priority\": 2,\n" +
" \"condition\": {\"operator\": \"GE\", \"leftOperand\": \"@@89\", \"rightOperand\": 281}\n" +
" }\n" +
" ]\n" +
"}";

// Rule rule1 = JSON.parseObject(json1, new TypeReference() {
// });
Rule rule1 = JSON.parseObject(json1, Rule.class);

System.out.println(rule1);
}

public static class ConditionDeserializer implements ObjectReader {
@Override
public Object readObject(JSONReader jsonReader, Type type, Object o, long l) {
// 非叶子节点
if (jsonReader.isArray()) {
return jsonReader.readArray(Rule.class);
} else if (jsonReader.isObject()) {
// 如果是对象，则解析为 Rule
return jsonReader.read(Expr.class);
} else if (jsonReader.isNumber()) {
// 如果是数字，直接返回数值
return jsonReader.getNumber().longValue();
} else if (jsonReader.isString()) {
// 如果是字符串，直接返回字符串
return jsonReader.readString();
} else {
throw new JSONException("Unsupported condition type：" + jsonReader.current());
}
}
}

@Data
public static class Rule {
private String key;
private String type;
private Object action;
private int priority;

// Condition 可以是三种类型：Rule、Expr、String 或 Integer
@JSONField(deserializeUsing = ConditionDeserializer.class)
private Object condition;

public void setCondition(Object condition) {
this.condition = condition;
}
}

@Data
public static class Expr {
private Object leftOperand;
private String operator;
private Object rightOperand;
}
}
```

#### 附加信息
*如果你还有其他需要提供的信息，可以在这里填写（可以提供截图、视频等）。*

Reproduce the nested numeric condition case from the issue's main method using Fastjson2 2.0.53, then trace the stack through FieldReaderObject, ObjectReader5, and JSONReader.readArray. Compare it with the string condition case; done means numeric values nested in condition deserialize without the reported illegal fieldName error.
