ApifyRequestQueueClient.batch_add_requests cannot handle more than 25 requests

This is an intentional limitation of the Apify API. Javascript client bypasses this, the python one doesn't.

JS client handles this here, ideally we should port the same logic:

https://github.com/apify/apify-client-js/blob/8c7d2d7327065d337cce7958df8580469aed3c18/src/resource_clients/request_queue.ts#L257

Once this is done we can revert the apify/apify-sdk-python#261 hotfix.
