doctl registry with multiple registry

I've encountered an issue when attempting to use `doctl `with multiple DigitalOcean Container Registries. Previously, I relied on doctl to retrieve registry information and untag unused images. However, with the presence of multiple registries in my account, using commands that implicitly target a single registry (e.g., doctl registry get) now results in the following error:

> `Error: failed to get registry: GET https://api.digitalocean.com/v2/registry: 412 (request ) This API is not supported if you have created multiple registries. Please use ‘/v2/registries/{registry_name}’ instead. Refer to https://docs.digitalocean.com/reference/api/digitalocean/#tag/Container-Registry for more info.
> `

This prevents me from performing essential registry management tasks via doctl for any of my registries, as I cannot specify which registry I intend to interact with for these general commands. I am effectively blocked from using doctl for my registry workflows.

Environment:

- doctl version: 1.133.0-release
- OS: macOS 15.5
- Installation method: Homebrew
