Folder pages not generated for folders that only contain subfolders or are empty about quartz

[huffn]

Edit: My cache hadn't cleared when I was testing if it would work for empty folders with a subdirectory. The isDirectChild change doesn't fix the folders from not being generated if there aren't any markdown files. I'll play around a little more to see if there is another spot where it is filtering out no direct children for folder pages.

In FolderContent.tsx I was able to fix this problem by modifying the allPagesInFolder filter by changing the return from return prefixed && isDirectChild to return prefixed || isDirectChild

The isDirectChild check is filtering out any files in subfolders. I was having a similar bug since the description for Folder and Tag Listings claims:

Quartz will generate an index page for all the pages under that folder. This includes any content that is multiple levels deep.

But my folder pages first returned the 404 since I didn't have any files in the higher up directories. I ended up putting a markdown file in that folder, but it still wasn't showing the sub directories. So this fix makes sure that subdirectories aren't filtered out when the folder pages are generated.
