No longer possible to pass path to local dataset script directory

[albertvillanova]

Since commit 08a65ff8ac90731538efc94cf89bb4285d6d3e77 (19/March/2021) it is no longer possible to pass the path to a local dataset script folder.

Before, there was a text input like this:

Please enter the path to the folder where the dataset_infos.json file was generated: "/path/to/dataset/"

This no longer appears.
