[Workers] Update GitHub Actions example to use wrangler-action@v4 and note build step

[Guardiansoftiktok]

Summary

Updates the GitHub Actions example on the Workers CI/CD page so that:

1. cloudflare/wrangler-action@v3 → @v4 — matches the current default of the action (Wrangler v4). Users copying the example today land on the older major version.
2. Adds a commented-out build step — # - name: Build / # run: npm ci && npm run build. This mirrors the pattern already used on the Pages direct-upload CI page, so users deploying Workers built with a bundler or framework (Tanstack Start, Next-on-Workers, Astro, etc.) see where to hook the build in. Without it, users have been hitting runtime errors like entry-point file at "..." was not found because the example doesn't mention a build.
3. Renames the step Build & Deploy Worker → Deploy Worker — the old name implied a build was happening inside the wrangler-action step, which was misleading.

Reported in cloudflare/wrangler-action#408.

Test plan

• Change is contained inside a YAML code block — no MDX syntax touched, renders unchanged
• Frontmatter unchanged
• Matches existing house style already used on the Pages CI page

Rebased onto production after #33536 merged. That PR (thanks!) already handled the @v3 → @v4 bump on the same example, so I've dropped that hunk. What remains here is:

1. A commented-out build-step block matching the pattern used on the Pages direct-upload CI page — so users deploying Workers built with a bundler or framework (Tanstack Start, Next-on-Workers, Astro, etc.) can see where to hook a build in. This is the original user complaint from cloudflare/wrangler-action#408.
2. Named the checkout step (- name: Checkout) and renamed the deploy step (Deploy Worker instead of Build & Deploy Worker) so the step name matches what the step actually does now that build is a separate marker.

Happy to trim further if the smaller scope after #33536 makes any of this not worth carrying.
