Somewhat annoying, that the configuration is spread out across 2 config files of 2 separate programs (git and ssh) and that the `insteadOf` `url` must match the `Host` in `.ssh/config`, which leaves a lot of room for mistakes and is fiddly, but at least this method works well!

Edit: Hmm it seems to ask me over and over again for my password for a key at every pull or push. Maybe this method somehow disables memorizing the SSH identity?
