Hetzner's legacy DNS console (dns.hetzner.com) and its old DNS API have
been permanently shut down. All DNS zone management has been migrated
entirely to the main Hetzner Cloud Console.
Since I hadn't made any changes in the last couple of months I was
simply not affected by that change until very recently.
So, this change drops the 3rd-party provider I had used previously and
now applies the official `hcloud`-provider.
The migrations was a bit of a hassle, because I had to manually remove
the obsolete references from the Tofu-state. Then I checked the migrated
sources and decided to simply drop the migrated DNS-zones altogether and
simply run `tofu apply` once more.
