通过设置 System.setProperty("seata.config.name","/abc/registry.conf") 设置registry.conf的路径不生效

目的时为了在类路径的abc目录下放置registry.conf，但通过设置 System.setProperty("seata.config.name","/abc/registry.conf")后，registry.conf的内容不生效，同时registry.conf里也设置了config.file.name="/abc/file.conf"，file.conf内容也不生效！

registry.conf内容如下：
```
registry {
# file 、nacos 、eureka、redis、zk
type = "nacos"

nacos {
application="seata-server"
serverAddr="192.168.137.199:8848"
namespace=""
cluster="default"
group="SEATA_GROUP"
username="nacos"
password="nacos"
}
}

config {
# file、nacos 、apollo、zk
type = "file"
file {
name = "/abc/file.conf"
}
}
```

Start by reproducing the issue with System.setProperty("seata.config.name","/abc/registry.conf") and the registry.conf and file.conf paths shown in the report. Trace Seata's configuration-loading entry point to determine why both classpath configuration files are ignored, then verify that the configured registry and file settings take effect. Confirm the behavior with a focused regression test if the repository provides a suitable configuration test location.
