As reported in https://github.com/localstack/localstack/issues/6659#issuecomment-1630932643_, `HeadObject` does not respect `ChecksumMode`. 


```shell

    "Location": "http://test-bucket.s3.localhost.localstack.cloud:4566/"

}

# SHA256 missing here
at 09:32:20 ➜ aws --endpoint-url=http://localhost:4566 s3api head-object --bucket test-bucket --key file.json --checksum-mode Enabled

    "Metadata": {}
}
```

Note the equivalent response from S3 actual includes the SHA256 value
