It's also a bit outdated. OpenSSH supports FIDO2 natively, so all this gnupg stuff is unnecessary for ssh. One can even use yubikey-backed ssh keys for commit signing.
And the best thing is that you can create several different ssh keys this way, each with a different password, if that's something you prefer. Then you need to type the password _and_ touch the yubikey.
