Subject: [PATCH] WordPress PR Previewer: simplify the Blueprint

Replaces a series of custom steps meant to unzip and configure WordPress with passinf the build zip as a preferredVersion.

To test, go to the WordPress PR previewer locally and try previewing one of the recent PRs. Confirm the installed WordPress versions is indeed not the latest stable.

Do not merge until these PRs are merged:

* #1423
* #1424
* #1425
* #1426
* #1427
