recursive checkout action not work as exptected.

[liudonghua123]

I tried to use

    - uses: actions/checkout@v2
      with:
        submodules: 'recursive'

or

    - uses: actions/checkout@v2
      with:
        submodules: 'recursive'
        fetch-depth: '0'

But during the latter build process, it always failed with something error message like

Error: Command failed: git describe --tags
fatal: No names found, cannot describe anything.

see https://github.com/liudonghua123/dpo-voyager/runs/662309034?check_suite_focus=true.

And in the end I need to rewrite the checkout steps like the following to make the build process success.

    - uses: actions/checkout@v2
      with:
        submodules: 'recursive'
    - run: git fetch --prune --unshallow

Is there any options to make git work as --prune --unshallow?
