Using impit for for `dataset.push_items` can cause `Error(IncompleteMessage)`

[Pijukatel]

Now impit is used as default client for apify-client-python
It seems that it can cause some errors for dataset operations

for example:

  File "/usr/local/lib/python3.13/site-packages/apify_client/clients/resource_clients/dataset.py", line 1044, in push_items
    await self.http_client.call(
    ...<7 lines>...
    )
  File "/usr/local/lib/python3.13/site-packages/apify_client/_http_client.py", line 276, in call
    return await retry_with_exp_backoff_async(
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    ...<5 lines>...
    )
    ^
  File "/usr/local/lib/python3.13/site-packages/apify_client/_utils.py", line 201, in retry_with_exp_backoff_async
    return await async_func(stop_retrying, attempt)
           ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "/usr/local/lib/python3.13/site-packages/apify_client/_http_client.py", line 240, in _make_request
    response = await impit_async_client.request(
               ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    ...<6 lines>...
    )
    ^
impit.HTTPError: The internal HTTP library has thrown an error:
reqwest::Error {
    kind: Request,
    url: "http://10.0.46.51:8010/v2/datasets/oCWSWFberpn5TiAhH/items",
    source: hyper_util::client::legacy::Error(
        SendRequest,
        hyper::Error(
            IncompleteMessage,
        ),
    ),
}

It might have been some temporary network issue, and as it was not easily reproducible later, I am not sure how the Httpx-based client behaves in such a situation.
