Support version preview urls in Cloudflare workers

[Phoenixmatrix]

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).

We can pull this from wrangler artifacts.
