Patch file path, content size and checksum in distributions during import batch

[imsdu]

Motivation
At least the path should change in distributions, the other may also change as for example in some cases they also may be absent.

"distribution": {
    "@type": "DataDownload",
    "atLocation": {
      "@type": "Location",
      "location": "/path/bbp/atlas/b/7/a/3/4/4/6/1/L1_HAC%7CcNAC_INH_densities_v3.nrrd",
      "store": {
        "@id": "https://bbp.epfl.ch/neurosciencegraph/data/xxx",
        "@type": "RemoteDiskStorage",
        "_rev": 1
      }
    },
    "contentSize": {
      "unitCode": "bytes",
      "value": 1920289
    },
    "contentUrl": "https://bbp.epfl.ch/nexus/v1/files/bbp/project/...",
    "digest": {
      "algorithm": "SHA-256",
      "value": "6e9eb5e1169ee937c37651e7ff6c60de47dc3c2e58a5d1cf22c6ee44d2023b50"
    },
    "encodingFormat": "application/nrrd",
    "name": "L1_HAC|cNAC_INH_densities_v3.nrrd"
  }

Acceptance criteria

1. The distribution is patched with the information from the file
2. If the file can't be resolved, we keep the distribution as it was

Implementation notes
We already patch the contentUrl where we extract the project and file id.
This can be used to get the file and its attributes for this other step
