Datasets that are disabled for download can be downloaded through exporting result in workflows.

Problem:
Datasets that are disabled for download can still be used by other users that have access to the dataset. Those users can utilize the dataset and export the results, which would have the effect of downloading the dataset.

Steps to reproduce:
Use a dataset that is disabled for download, execute it, and export the result.

Solution:
Downstream operators that come from dataset operators should not be able to export result. For example, in the image below, if the upper CSV file scan uses a dataset with download disabled, all downstream operators (highlighted) should not be able to export the result.

It's an important issue to solve. We can also think about whether we want to something on the result panel (on the frontend) for such an operator to prevent users from downloading its results easily.
