Order.spec.replaces

Replaces is the ARI CertID (RFC 9773 §4.1) of the certificate that this Order is intended to replace. When set, cert-manager will include the "replaces" field on the newOrder request to the ACME server if and only if the server advertises ARI support in its directory. The CertID has the form "base64url(AKI).base64url(serial)" and is derived locally from the currently issued leaf certificate.
