DigitalOcean Container Registry GET/DELETE API Calls Failing

I’m running into a problem with **DigitalOcean Container Registries** using `doctl`.

* Creating a registry (`doctl registry create`) works fine.
* However, `doctl registry get` and `doctl registry delete` fail with a **412 error**:

```
Error retrieving container registry: GET https://api.digitalocean.com/v2/registry: 412
This API is not supported if you have created multiple registries. Please use '/v2/registries' instead.
```

I also tested with Terraform — the same GET request fails there too. This confirms it’s an issue with the **DigitalOcean API**, not the tools or our configuration.

**Environment:**

doctl version 1.99.0-release
OS: Win11

**Additional Details:**

* Tested with multiple Terraform registry configurations — same result.
