ci: read the org-scoped ZEGIT_CI_PACKAGE_TOKEN, not a repo-local name

The publish path failed at registry login on every dispatch (runs 18,
20) because it read `secrets.ZEGIT_PACKAGE_TOKEN`, a name that exists
nowhere. The package-write token every zegit-zoo image workflow uses is
ZEGIT_CI_PACKAGE_TOKEN, held above repository scope, so this repository
can read it under that name — no second token, no second copy to rotate.
