Create canary tests for Cloudflare E2E and integration tests #20874

Description

We need to check against newer compatibility dates as over time it could be that certain things are getting deprecated or removed.

A basic wrangler.jsonc has following attributes:

{
  "name": "hono-sdk-worker",
  "compatibility_date": "2025-06-17",
}

Where the compatibility_date is always set to a fixed date in our tests. It would be nice if we would run the Cloudflare E2E and integration tests as canary variant with the latest compatibility_date. It is technically not treated as canary, but it would be the same behavior. Alternatives can and should be investigated as well.
