在一键脚本中提供关闭 GitHub Proxy 的选项

[scientificworld]

Please make sure of the following things

• [X] I have read the documentation.
• [X] I'm sure there are no duplicate issues or discussions.
• [X] I'm sure this feature is not implemented.
• [X] I'm sure it's a reasonable and popular requirement.

Description of the feature / 需求描述

在大部分网络环境中，不存在对 GitHub 资源的访问问题，依赖于代理服务反而会降低稳定性。

以 https://mirror.ghproxy.com/https://github.com/xhofe/alist/releases/latest/download/alist-linux-musl-amd64.tar.gz 这个链接为例，目前它处于 502 状态，导致一键脚本不可用，而将 GH_PROXY 变量设置为空字符串以后即可正常下载。

Suggested solution / 实现思路

添加类似于 --disable-ghproxy 的选项。

有道理，不过我的建议是

curl -fsSL "https://alist.nn.ci/v3.sh" | env GH_PROXY='https://hub.gitmirror.com/' bash -s install

且在文件内抹除以下内容

GH_PROXY='https://mirror.ghproxy.com/'

才能在不设置env的情况下 直接连接到github 使用env自定义的好处是，官方不用维护增删反代列表，只需用户找到符合格式的地址进行下载就行
