we need to upgrade to 2.2.0 which completely break the RegistrationResult model. We need to reimplement this properly like with https://github.com/Yubico/java-webauthn-server/blob/main/webauthn-server-demo/src/main/java/demo/webauthn/InMemoryRegistrationStorage.java, https://github.com/Yubico/java-webauthn-server/blob/main/webauthn-server-demo/src/main/java/demo/webauthn/data/CredentialRegistration.java, https://github.com/Yubico/java-webauthn-server
