fs: fix missing file name with withFileTypes option of readdir

The issue was caused by a modification in PR nodejs#51021, which included changes
to the documentation for parentPath and modifications to display the filepath.
I have retained the content related to the documentation and removed the
filepath part.

Fixes: nodejs#52441
