Fix CI: use correct API v1 endpoint for package registry deletion

The DELETE endpoint for Forgejo generic packages is /api/v1/packages/
while the upload (PUT) endpoint is /api/packages/. Using the wrong
endpoint caused silent failures, leaving stale latest.json in the
registry. Also fail the CI step explicitly on upload failure.
