Integrity field uses 'value' instead of 'hash'

[AissaGeek]

Description:

There is a bug in the get_hash_info method of the DownloadWorker class in downloader/__init__.py. The integrity field in the job payload uses 'value' instead of 'hash', which may lead to incorrect hash extraction.

Steps to reproduce

Consider this payload

    }
  ],

}

content has no attribute hash, but value instead

Suggested solution

integrity = job.get('payload', {}).get('properties', {}).get('integrity', {})
expected_hash = integrity.get('hash') or integrity.get('value')
