フォルダと同じ名前のファイルを含むフォルダのみを探す

同じ名前（および拡張子）を持つマークダウンファイルを含むすべての.mdサブフォルダを見つけたいです。

例: 次のサブフォルダーを探したいと思います。

Apple/Banana/Orange      #Apple/Banana/Orange/Orange.md exists
Apple/Banana             #Apple/Banana/Banana.md exists
Apple/Banana/Papaya      #Apple/Banana/Papaya/Papaya.md exists

• 注：ディレクトリの下に別のファイルまたはサブディレクトリがある可能性があります。

どんな提案がありますか？

問題の解決策は、次のコードを使用してテストできます。
