extension store ignores proxy settings

[teidesu]

Reproduction steps

1. be in network conditions where access to the extensions cdn (*.digitaloceanspaces.com) is restricted when requested without a proxy
2. configure an http proxy "proxy": "127.0.0.1:7891" in settings.json
3. try installing an extension

Current vs. Expected behavior

current behavior: the installation fails with a timeout with no clear indication of the error, the logs state that the connection was timed out.
expected behavior: the extension is successfully downloaded through a proxy
