fix: rename workflow to Update Website and guard verify step (#282)

- Rename workflow name from "Deploy Website" to "Update Website"
- Rename job/step names from "Build & Deploy Website" to "Build & Update Website"
- Add same `if: secrets.SSH_PRIVATE_KEY != ''` guard to Verify Website step
  so it is skipped when the deploy step is also skipped, preventing the
  verify from failing on a stale website version
