希望新增部署自定义子路径，方便nginx做子路径反代 Nginx with Subpath (example.org/cloudreve)

A clear and concise description of what the problem is. Ex. I'm always frustrated when [...]
nginx要反代很多服务，如果只把域名根路径“/”全给cloudreve服务，其他服务子路径比如example.org/jellyfin在清空网站缓存的前提下，直接访问example.org/jellyfin是可以正常访问的，但是一旦同时打开根路径example.org/的cloudreve服务，之后所有路径都会全部导向cloudreve服务
When configuring nginx to reverse proxy multiple services, if you only pass the root path "/" to the cloudreve service and leave other service paths like example.org/jellyfin untouched, accessing example.org/jellyfin directly should work fine after clearing the website cache. However, once you also open the root path example.org/ for the cloudreve service, all subsequent paths will be redirected to the cloudreve service.

希望能增加cloudreve部署的子路径自定义设置，支持本机压缩包部署、docker部署的子路径配置
I suggest adding customizable sub-path settings for deploying Cloudreve, supporting sub-path configurations for both local compressed package deployment and Docker deployment.

同时希望在使用文档中增加nginx子路径反代配置示例
I also recommend including examples of nginx sub-path reverse proxy configurations in the usage documentation.
