logger命令执行成功, 实际项目的日志级别仍然是原来的级别

- [ ] 我已经在 [issues](https://github.com/alibaba/arthas/issues) 里搜索，没有重复的issue。

### 环境信息

* `arthas-boot.jar` 或者 `as.sh` 的版本： arthas-all-3.6.1
* Arthas 版本: 3.6.1
* 操作系统版本: Linux version 3.10.0-1160.42.2.el7.x86_64
* 目标进程的JVM版本: OpenJDK 64-Bit Server VM (build 25.312-b07, mixed mode)
* 执行`arthas-boot`的版本: arthas-all-3.6.1
arthas-spring-boot-starter: 3.3.6

### 重现问题的步骤

[arthas@15856]$ logger -c b4aac2 --name ROOT --level INFO
Update logger level success.

[arthas@15856]$ logger
name root
class org.apache.logging.log4j.core.config.LoggerConfig
classLoader sun.misc.Launcher$AppClassLoader@b4aac2
classLoaderHash b4aac2
level INFO

### 期望的结果

期望日志级别能动态修改成INFO级别

### 实际运行的结果

虽然命令执行成功, 实际项目仍然是DEBUG级别日志.

```
把异常信息贴到这里
```

Start with the `logger` command using the reported Arthas 3.6.1 environment and reproduce `logger -c b4aac2 --name ROOT --level INFO`, followed by `logger`. Trace the command's Log4j2 level-update handling and verify that the target application's effective logging changes from DEBUG to INFO, not only the reported logger configuration.
