LibGit2 Fails in AutoMerge

[anirudh2]

I'm running into issues during the cloning step of verifying that we can add the package.

SSH host verification: the identity of the server `github.com:22` does not match its known hosts record. Someone could be trying to man-in-the-middle your connection. It is also possible that the server has changed its key, in which case you should check with the server administrator and if they confirm that the key has been changed, update your known hosts file.

I've tried to follow what what outlined in #245, but that hasn't worked for me.

All relevant repos are public, including the relevant automerge.yml. Any suggestions would be very much appreciated!
