[Bug]: Blog article navigation links are backwards

Summary

The "Previous" and "Next" blog navigation links on https://react.dev/blog appear to be reversed.

Page

https://react.dev/blog/[date]/[articalName]

Details

❌ Current Behavior:

• The "Previous" link points to a newer post.
  -The "Next" link points to an older post.

✅ Expected Behavior:
-"Previous" should go to an older post.
-"Next" should go to a newer post — matching typical blog UX.

Example:
On this post:
https://react.dev/blog/2024/04/25/react-19](https://react.dev/blog/2025/04/23/react-labs-view-transitions-activity-and-more

At the bottom:
-"Previous" goes to a newer post
-"Next" goes to an older post

從 https://react.dev/blog/[date]/[articalName] 的部落格文章頁面開始，追蹤 Previous/Next 導覽。將連結與相鄰文章的日期進行比較；當 Previous 指向較舊的文章而 Next 指向較新的文章時，即表示完成。
