Describe the Bug

Running the following command fails with a CLI validation error:

npx wrangler queues subscription create --source images --events image.uploaded

Error:
Invalid values:
Argument: source, Given: "images", Choices: "kv", "r2", "superSlurper", "vectorize", "workersAi.model", "workersBuilds.worker", "workflows.workflow"

The images source is not in the hardcoded choices list for the --source argument, so the CLI rejects it before even making an API call.

However, the Cloudflare REST API (POST /accounts/{account_id}/event_subscriptions/subscriptions) and the Cloudflare Dashboard (Queues → queue → Subscriptions → Subscribe to events → Source: Images) both fully support the images source.

Steps to reproduce:

1. Have a Cloudflare Queue and a Cloudflare Images account
2. Run: npx wrangler queues subscription create my-queue --source images --events image.uploaded
3. CLI errors with "Invalid values" — never reaches the API

Expected behavior: The command succeeds and creates the event subscription, matching what the REST API and Dashboard support.

Actual behavior: CLI rejects images as an invalid choice before making any API call.

Root cause (already identified): The EventSourceType enum in packages/wrangler/src/queues/subscription-types.ts is missing IMAGES = "images". A fix has been prepared in the linked PR.

Please provide any relevant error logs
