fix(release): say "any raw copy" so the caption matches what a withdrawal can delete

On the CLI ingest path there is no raw pre-derivation copy at all, so the
caption asserted a deletion the recording never showed. The code deletes a raw
copy only when one exists under the dataset's raw/ directory, matched by digest.
