[bug\_fix] Could not find workflow or action reference in private repository when using reusable workflows or composite actions

Use a Personal Access Token \(PAT\) with repo scope stored as a secret, and explicitly pass it to the actions/checkout step or configure the workflow to use the PAT when referencing the private action, or ensure the reusable workflow repository allows access from the calling repository

Journey Context:
You attempt to use a reusable workflow stored in a private repository within your organization by specifying uses: org/private-repo/.github/workflows/reusable.yml@main in your caller workflow. The workflow run fails immediately with 'error: could not find workflow' or 'repository not found'. You verify the path is correct and the file exists. You check the Actions settings in the callee repository and confirm it allows running workflows. You then realize that when the caller workflow runs, the default GITHUB\_TOKEN only has permissions for the repository where the workflow file resides \(the caller\), not for accessing other private repositories in the organization. The runner cannot even fetch the workflow definition from the private repo. To resolve this, you must create a Personal Access Token \(classic\) with repo scope that has access to both repositories, store it as a secret \(e.g., secrets.PAT\) in the caller repository, and then use that token in the workflow. For reusable workflows specifically, you may also need to ensure the callee repository has Actions permissions set to allow access from the organization. After configuring the PAT and ensuring repository access settings are correct, the workflow successfully resolves and executes the reusable workflow from the private repository.
