vscode remote ssh使用proxy

由于网络问题导致vscode server总是更新失败，可以考虑配置代理解决。

设置，搜索 proxy，切换到 Remote SSH，勾选

Remote.SSH: Use Curl And Wget Configuration Files
Respect configuration from remote environment's 'curlrc' and 'wgetrc' files (placed in their respective default locations). Enabling this setting may be useful in certain cases (i.e: proxy configuration) but can interfere with this extension's operation.

创建或编辑 ~/.wgetrc 文件，写入代理配置，例如：

use_proxy=yes
http_proxy=192.168.3.100:1080
https_proxy=192.168.3.100:1080
