Support cache-dependency-paths outside the current directory

Description:

I’m building a composite Action which uses actions/setup-python internally. When specifying the requirements.txt from the action setting up Python fails, though I thiiink I’m passing the right values.

Here’s what I’ve got:

    - name: Set up Python
      uses: actions/setup-python@v3
      with:
        python-version: '3.10'
        cache: pip
        cache-dependency-path: ${{ github.action_path }}/requirements.txt

Here’s the error I get:

No file in /home/runner/work/sr2022-comp/sr2022-comp matched to [/home/runner/work/_actions/PeterJCLaw/srcomp-validate-action/bd809ff12b77607cc2f0ebbd035d6f0a5c8d32fc/requirements.txt], make sure you have checked out the target repository

sr2022-comp is the repo I’m using to test the action, srcomp-validate-action is the action.

My specific use-case only has a couple of dependencies so #351 would likely work as a fix, though I can imagine that a more complex scenario would want this to work.

Thanks for your replies. For completeness the repos in question are:

• https://github.com/PeterJCLaw/srcomp-validate-action/
• https://github.com/srobo/sr2022-comp/ (specifically https://github.com/srobo/sr2022-comp/pull/5)

I’ve raised https://github.com/actions/toolkit/issues/1035 for the underlying issue.

Hello @PeterJCLaw. For now I’m going to close the pull request because the root cause of the issue comes from the toolkit repository. If you have any concerns feel free to ping us.
