Automatic certbot renew on a Mac

It seems like everyone is using cron for setting up certbot renew on Macs but I couldn't find anyone doing it with launchd. The other file in this Gist is the service file.

The documentation on the Let's Encrypt site actually recommends having it run twice a day (12 hours apart) but I've found that once a day is more than sufficient since if it fails it still has another 29 days to succeed.
