So Certbot was installed using the PPA, but two of the Certbot packages are quite out of date and out of sync with the others.
Plus, python3-certbot-dns-digitalocean isn’t installed at all, which means it must be installed some other way, and its version might also be out of sync.
I guess you should upgrade your packages, apt install python3-certbot-dns-digitalocean, and hunt down the other copy of the DigitalOcean plugin and delete it (carefully).
(The python3-certbot-dns-digitalocean package is version 0.23.0, but it’s supposed to be. The plugin hasn’t changed recently and the PPA is managed in a compatible way.)
