blobs: fix outdated comment about file format

the wrong info here was rather misleading, especially when encountering errors
just talking about "blobs" when the actual problem is with a chunk.

chunks did originally have their own magic values, but that got removed in

4ee8f53d07bf0becf19a22cf4f4674558a4d128c "remove DataChunk file format - use DataBlob instead"

back in 2019, before the 0.1.1 release(!)
