Description
When a registry has a DNL suffix, the registry_name does not match the prefix of the regional endpoint hostname. This fix uses registry.login_server.split('.')[0] (the login server hostname before the first dot) instead of registry_name when constructing the regional endpoint prefix, so that DNL registries correctly resolve to their regional login endpoint.

Use login_server hostname (before the first dot) instead of registry_name
when building the regional endpoint prefix. This accounts for registries
with a DNL (Dedicated Network Link) suffix in their login server name.
