[dns-wg] Update RIPE's DNS Zonemaster

Hi, RIPE's DNS Zonemaster version might be outdated, because it does not support DNSSEC algorithm ED25519. This is the error message: Signature for DNSKEY with tag 52537 failed to verify with error 'Unknown cryptographic algorithm'. https://dnscheck.ripe.net/test/328db6c75665721b But the Zonemaster software (Versions: engine 4.0.3, backend 6.0.2, GUI 3.2.1) has already support for DNSSEC algorithm ED2551: https://www.zonemaster.net/result/c1607f01d96a8d60 It would be good if RIPE's Zonemaster could also list its version numbers. cheers, -Arsen
