fix: update the first workflow to the latest version

[HairlessVillager]

The code in the documentation is outdated. When I paste the code from the original documentation and run pnpm run build:dev, it will report an error:

However, I found that there was no need to paste the code actually, because the file already contained code that was functional. Therefore, I revised the documentation and added relevant instructions.

Additionally, perhaps we could consider adding a community guideline: Any pull request (PR) that modifies code should also modify the corresponding documentation to avoid inconsistencies between code behavior and documentation.

Closed as the docs has been fixed.
