Replace cargo feed with Azure Artifacts feed (#97)

For ~ compliance reasons ~ we need use an Azure Artifacts feed for our cargo feed. We can't just use it in our internal pipeline either, we need to have the _default_ `.cargo/config.toml` use an artifacts feed too. 🤷

This points our feed at https://dev.azure.com/shine-oss/sudo/_artifacts/feed/Sudo_PublicPackages, which _should_ work publicly now.
