Provide a description of requested docs changes

It is possible to specify "chunk_overlap" as a parameter for document creation in the Knowledge API.
However, this is not mentioned in the API specifications, so an addition is required.

ex: Create a Document from a Fileにおけるchunk_overlap

curl \
  --location \
  --request POST \
  "http://localhost/v1/datasets/${dataset_id}/document/create-by-file" \
  --header "Authorization: Bearer ${api_key}" \
  --form 'data={
    "indexing_technique": "high_quality",
    "process_rule": {
      "rules": {
        "pre_processing_rules": [
          { "id": "remove_extra_spaces", "enabled": true },
          { "id": "remove_urls_emails",  "enabled": true }
        ],
        "segmentation": {
          "separator": "###",
          "max_tokens": 500,
          "chunk_overlap": 100
        }
      },
      "mode": "custom"
    }
  };type=application/json' \
  --form 'file=@"test.txt"'
