Support version preview urls in Cloudflare workers

Cloudflare Workers now support preview urls similar to Cloudflare Pages. Unfortunately wrangler's output for those is slightly different than the output from Pages, so the regex doesn't catch it to store in deployment-url.

Example of Wrangler's output:

```
Version Preview URL: https://an21s8iyi-worker-test.mydomain.workers.dev/
```

Without that, it's difficult to get access to the url in a version preview (it's available in the output, but its tough to capture it to use elsewhere in my GitHub action).

Start by locating the regex that parses Wrangler and Pages output for deployment-url, then compare its expected format with the reported "Version Preview URL" line. Verify that a Cloudflare Workers version preview URL is captured and exposed through the GitHub Action's deployment-url output, using the repository's existing tests or workflow checks if available.
