🧐[Question] Linux，开启GitHub加速时，无法使用git clone克隆版本库

### 🧐 问题描述(Description)
开启GitHub加速时，无法使用git clone克隆版本库，当关掉加速时，没有问题。
就比如，执行命令`git clone git@github.com:BeyondDimension/SteamTools.git`，输出如下：
```
正克隆到 'SteamTools'...
ssh: connect to host github.com port 22: Connection refused
fatal: 无法读取远程仓库。

请确认您有正确的访问权限并且仓库存在。
```
### 🚑 其他信息(Other Information)
- 程序版本(Program Version): Watt Toolkit x64 v2.8.4 β for Linux
- 系统版本号(OS Version): Ubuntu 20.04.5 LTS

Start by reproducing `git clone git@github.com:BeyondDimension/SteamTools.git` on Watt Toolkit x64 v2.8.4 β for Linux under Ubuntu 20.04.5 with GitHub acceleration enabled and disabled. Trace the acceleration path around the SSH connection to port 22; done means cloning succeeds while acceleration remains enabled, with the affected configuration or limitation documented.
