Storage Details for a folder

Nobody has claimed this yet.

### Description of the new feature / enhancement

The goal of this feature would be to view more details about the disk space used by a folder. In addition to seeing the space used by the folder itself (right-click -> Properties), we could also see the space used by its subfolders and files.

The script support large files (MB and GB); support for small files (kB) could also be implemented. Another possible enhancement would be to add recursive folder searching (myFolder -> mySubfolder -> mySubSubfolder -> ...). However, performance could be impacted by excessively long searches.

### Scenario when this would be used?

I needed to free up space on my local drive for an update. I wasn't sure exactly which files or folders to delete, so I started looking for them manually. To save a lot of time spent searching for large files, I came up with an idea. I created a script that I think could help others and that could even be paired with a nice interface.

### Supporting information

Note: Sorry, my PC is a french PC 😄

The issue names no file, utility, entry point, or test; start by identifying the PowerToys area responsible for folder actions and reviewing the described script and screenshots. Done requires an agreed scope for folder and subfolder size reporting, small-file support, recursion limits, performance, and the user interface.
