datastore-s3 throws the wrong error when a file isn't found on s3

When using datastore-s3, calling `helia.pins.add` or `helia.pins.ls` fails with a "NoSuchKey" error

```
err: {
"type": "GetFailedError",
"message": "NoSuchKey: The specified key does not exist.",
```

If a file isn't found a "NotFoundError" is gracefully handled, but a GetFailedError throws. datastore-s3's "get" method currently throws a GetFailedError when a given file isn't found.

This is because the 404 status check doesn't line up with the response from s3 ([this line](https://github.com/ipfs/js-stores/blob/main/packages/datastore-s3/src/index.ts#L162))

Applied the following patch to fix:

```
