Update workers routes validity

Actual Behavior

The docs clearly state that a route pattern must include the zone name:

cloudflare-docs/src/content/docs/workers/configuration/routing/routes.mdx

Lines 133 to 135 in b9e1d40

	#### Route patterns must include your zone
	If your zone is `example.com`, then the simplest possible route pattern you can have is `example.com`, which would match `http://example.com/` and `https://example.com/`, and nothing else. As with a URL, there is an implied path of `/` if you do not specify one.

Expected Behavior

Cloudflare for SaaS has long recommended a "*/*" route pattern:

cloudflare-docs/src/content/docs/cloudflare-for-platforms/cloudflare-for-saas/start/advanced-settings/worker-as-origin.mdx

Lines 23 to 28 in b9e1d40

	4. Decide whether you want traffic bound for your SaaS zone (`example.com`) to go to that Worker:
	* If *yes*, set the following values:
	* **Route**: `*/*` (routes everything — including custom hostnames — to the Worker).
	* **Worker**: Select the Worker used for your SaaS application.

This pattern doesn't include the zone name, but it works great! So I'm guessing the workers routes doc is just outdated.
