Title: Do not filter out .zip extensions from no-script datasets
Author: albertvillanova (MEMBER)
State: closed
Created: 2023-09-04T06:07:12Z

This PR is a hotfix of:
- #6207

That PR introduced the filtering out of `.zip` extensions. This PR reverts that.

Hot fix #6207.

Maybe we should do patch releases: the bug was introduced in 2.13.1.
