Support GitHub Actions update in cookiecutter-level project leveraging Dependabot CLI

Improve the CI pipeline by integrating a scheduled workflow that leverages the Dependabot CLI[^1] to update dependencies within the cookiecutter project. The project’s .yml template files include Jinja2 directives like `{% raw %}` and `{% endraw %}`, which require special handling.

To achieve this, the update process can be done with the following stages:

* **Identify Template Directives**:
* Detect lines in `.yml` file that contain the `{% raw %}` and `{% endraw %}` template Directives.
* **Project Configuration**:
* Configure the project to support running the Dependabot CLI
* **Execute Dependabot CLI**
* Run Dependabot CLI to update GitHub Actions dependencies within the configured project
* **Reintegrate Template Changes**:
* Reintegrate the updated lines back into the `.yml` files while preserving the original template structure.
* **Generate Pull Request**:
* Automatically generate a pull request with the updated .yml files.

This approach ensures the proper handling of templated files while keeping dependencies up-to-date

Start by locating the project’s .yml template files and the existing CI configuration, then review how {% raw %} and {% endraw %} directives are used. Configure a scheduled GitHub Actions workflow to run the Dependabot CLI, preserve the template structure, update GitHub Actions dependencies, and generate a pull request with the changed files.
