Subject: [PATCH] feat(release): replace the Google Play screenshots from a
 manual run

The track `listing`, from any tag, renders the screenshots and replaces
the Google Play listing images that differ, without a version or release.
App Store screenshots change only with a new App Store version.

Also runs the two Play screenshot tests, which sat after the __main__
block.
