I think this is sadly blocked on upstream issues: frewsxcv/rust-crates-index#37 which is itself caused by rust-lang/git2-rs#600

Sadly, not much we can do about them short of implementing SSH support ourselves instead of using the upstream crates, which doesn't seem like a good idea.

As soon as the upstream crates add SSH support, a cargo update on our end will fix it for cargo-semver-checks too. Alternatively, since this problem is fixed in cargo, merging our tool into cargo should fix the problem too. Linking #61 for that.
