Request: Need to reload scripts from packages (located in different folder than /Assets)

There doesn't seem to be an easy way to get these paths for cross-device setup. Seems like each developer will have to hardcode this themselves based on their project directory.

Tried something like this;
```
public static class ProjectPaths
{
public static string projectRoot => Path.GetDirectoryName(Application.dataPath);
public static string submodulesDirectory => Path.GetDirectoryName(Application.dataPath) + "/Submodules";
}
```
with , but doesn't seem to work.

首先跟踪 ProjectPaths 示例以及用于重新加载脚本、发现项目文件的入口点；该 issue 未指定文件或测试。复现一个将脚本放在 Assets 外部的 package 或 Submodules 文件夹中的配置，并将完成标准定义为跨设备路径发现，且不使用针对特定开发者的硬编码。
