github actions complete clone





     By default, github actions only do:


     git fetch ‐‐depth=1

This causes a small problem for my blog to create the index page.
In  my blog, I use git commit timestamps to track the create time
of each post.

Adding the following lines in workflows, it should be fine.


     ‐ uses: actions/checkout@v3
       with:
         fetch‐depth: 0  # 完整 clone
