Describe the Bug

We have a multi-worker setup with multiple environments defined on all of them. This breaks type generation, because wrangler cannot find the types for the services/durable objects referenced using <worker_name>-<environment>. This means that the generated type files now contain ugly unions between untyped services and the correctly typed ones. See the repro repo (especially worker/worker-configuration.d.ts) for an example.

Please provide any relevant error logs
