[Feature] Support adding third-party app store repository URLs directly

[gracelsy]

1Panel Version

v2.0.17

Please describe your needs or suggestions for improvements

1Panel第三方商店，希望直接支持添加第三方商店仓库链接(同时支持添加多个第三方商店仓库)

例如
Apps-key : okxlin
URL : https://gh.pt.uy/https://github.com/okxlin/appstore
Branch :localApps

同时因为多个第三方商店因某个应用重复，会导致已安装应用出错下图所示

希望第三方商店应用安装目录独立隔离，统一归至 /安装路径/1panel/resource/apps/thirdparty/${Apps-key}/，彻底解决多仓库应用重复导致的文件冲突、安装状态异常；
