Last updated does not work when deployed using GitHub Actions

Bug report

When deploying the docs to GitHub Pages using the GitHub Action jenkey2011/vuepress-deploy@master the "Last updated" value is never shown. Instead, when building and serving the docs using yarn build locally it is working as expected.

Steps to reproduce

Setup the GitHub jenkey2011/vuepress-deploy@master to deploy to GitHub Pages:

name: Build and Deploy
on:
  - push
jobs:
  build-and-deploy:
    runs-on: ubuntu-20.04
    steps:
      - name: Checkout
        uses: actions/checkout@master
      - name: vuepress-deploy
        uses: jenkey2011/vuepress-deploy@master
        env:
          ACCESS_TOKEN: ${{ secrets.ACCESS_TOKEN }}
          BUILD_SCRIPT: yarn && yarn build
          BUILD_DIR: src/.vuepress/dist

What is expected?

I would expect that also using the GitHub Action that the "Last updated" value is shown.

What is actually happening?

"Last updated" value is not shown. From what I see in the GitHub Action log is that the action does the right commands. Essentially it does the following:

yarn && yarn build
cd src/.vuepress/dist
git init
git commit [...]
git push -f [...]

I also have the same problem. Has it been resolved? It works fine when running yarn dev, but it does not work when building with github action.
