refactor(get-images-from-files): to return json array (#31)
CD / Release (push) Successful in 6s

Working with a proper JSON array is way better than the comma separated list, as the JSON array can be directly fed into subsequent GitHub actions, without re-formatting.

Changes don't need to be treated as breaking, as there is no productive consumer yet.
