WeakRef and FinalizationRegistry md doesnt follow site format

還沒有人認領這個 Issue。

Not sure it's a real issue, the article looks ok on chrome
maybe should check others, and epub
it looks like an incomplete conversion from html to md

- it uses html br and code tags (only the last part of the article)

- it breaks single sentences in several lines, html dont care but it prevent proper media based formatting in md

- no blank lines between sentences, it's not consistent with the rest of the site

開啟 WeakRef 和 FinalizationRegistry 文章的 Markdown 原始檔，並與網站的格式慣例進行比較。檢查回報的 HTML br 和 code 標籤、句子的換行方式，以及缺少的空白行，然後在 Chrome 和 EPUB 中驗證轉譯後的文章，以確認格式一致。
