fatal: not a git repository (or any parent up to mount point /github)

Please see the screenshot:

I run a workflow, that calls a reusable workflow, that in turn calls a composite action, and in turn that composite calls the tf docs action. The tf docs action eventually gets run like this:

- name: Terraform docs
   if: github.event_name == 'pull_request'
   uses: terraform-docs/[email protected]
   with:
     working-dir: ./terraform/terraform
     output-method: replace

My repo is checked out to a terraform directory, and in that I have a directory named terraform where the tf code is, like this:

- name: Checkout Code on PR
  if: |
  inputs.CodeCheckout == 'true' &&
  github.event_name == 'pull_request'
  uses: actions/checkout@v3
  with:
    path: terraform
    ref: ${{ github.event.pull_request.head.ref }}

I know the checkout is working OK as I can run terraform itself.

This is running on a ubuntu-latest github hosted runner.

I did some testing and can see the README.md is updated (ran a cat of the file from the github hosted runner after the failed tf docs action).

I have tried various settings for the tf docs action, such as find-dir, altering the working-dir (such as removing the ./ from the directory name), but it always fails with the same issue.
