Fix ship-queue ready tests after the pre-merge check got stricter (GST-2282) (#4271)

* Give the ship-queue ready tests complete pregate records

The notes-push and fresh-base suites wrote a one-check pregate record, which ready refuses as a partial run since #4258. They now write every registered check, as the other queue tests do.

* Add a changelog entry for the ship-queue ready test fix
