fix(release): let GitHub Release run despite SLSA final cosmetic failure

slsa-github-generator v2.1.0 final step fails exit 27 on Node 20
deprecation. Provenance is already generated and uploaded (generator +
upload-assets pass). Release job now runs if collect + attest succeed,
regardless of provenance final status.
