Adopt `potodo` in Makefile

I found a tool named potodo that provides same functionalities with part of our current Makefile commands but has better format. We can consider adopting this tool in our Makefile (or even storing the output as a file and updating it whenever a PR is merged).

• Listing untranslated files

  • make todo

    > make todo           
    for file in *.po */*.po; do echo $(msgattrib --untranslated $file | grep ^msgid | sed 1d | wc -l ) $file; done | grep -v ^0 | sort -gr

• Get overall progress

  • make progress

    > make progress
    4.4%
    

  • potodo | tail -n2 | head -n1 | cut -c 10- | sed 's/[%].*$/%/g'

    > potodo | tail -n2 | head -n1 | cut -c 10- |  sed 's/[%].*$/%/g'

先從儲存庫 Makefile 中用於 todo、fuzzy 和 progress 的命令開始，然後將它們的輸出與此 issue 中記錄的 potodo 範例進行比較。檢查在 Makefile 中應如何呼叫 potodo，以及其輸出應繼續作為命令結果，還是應儲存為檔案。選定的翻譯狀態命令能夠提供預期的 potodo 風格結果，即表示完成。
