HTTPS 443 超时

非自己的项目，不能使用 ssh 协议。

使用 HTTPS 443 端口超时

$ git clone https://github.com/liaoliaots/nestjs-redis.git

正克隆到 'nestjs-redis'...
fatal: 无法访问 'https://github.com/liaoliaots/nestjs-redis.git/'：Failed to connect to github.com port 443 after 75011 ms: Couldn't connect to server

在配置了 ssh 优化的基础上， 再在 ~/.gitconfig 中配置替换规则

[url "[email protected]:"]
    insteadOf = https://github.com/

再次测试， 成功
