Nheko doesn't respect system proxy settings on macOS

[EricZhang456]

Describe the bug

Nheko will only connect via the proxy server when the http_proxy and https_proxy environment variables are set and do not use the system proxy settings.

To Reproduce

1. Set a network proxy in System Preferences
2. Start up Nheko normally from Finder or Launchpad, Nheko will not use the proxy
3. Quit Nheko, open a terminal and set http_proxy and https_proxy
4. Relaunch Nheko with open /Applications/nheko.app
5. Nheko will connect via the proxy
