[Moon UI] Code Folder Sorting Issue

[benjamin-747]

Currently, folders are sorted with the latest records appearing at the end.
This needs to be changed so that the latest records are displayed at the top, improving usability and allowing users to access recent updates more quickly.

Note:
Git natively sorts the tree based on ASCII order, but the current implementation in the mono project differs from this behavior. The current sorting places the latest records at the end, whereas it should be modified to display the latest records at the top.
