Command to export existing records

[khromov]

It would be extremely useful if Bacon could also export records into the YAML format, making it possible to migrate records between porkbun domains! 🐷

Good news! This already exists, but it isn't documented. The command is bacon print <domain> and here's the code: https://github.com/jungaretti/bacon/blob/main/cmd/print.go

I need to add its details to Bacon's README.md

Excellent, thank you!

Let's leave this open until I make a PR to update the docs!
