The release workflow failed during verification: https://github.com/ko-build/ko/actions/runs/4386793516/jobs/7681560335
Looking at the release artifacts, here: https://github.com/ko-build/ko/releases/tag/v0.13.0
There's a multiple.intoto.jsonl uploaded by the provenance generation workflow, but the verification step seems to be looking for attestation.intoto.jsonl. Please let me know if this is a bug on ko's end, or if this is a misconfiguration, or a bug in the SLSA provenance generation.
