[MHHukiewitz]

Add PR Difficulty Rating workflow, see: aleph-im/aleph-sdk-python#76

[github-actions]

The PR adds a new GitHub workflow for rating the difficulty of pull requests, which requires an understanding of the GitHub Actions workflow structure and how it interacts with the repository. Furthermore, the new workflow utilizes a third-party action called "rate-my-pr/rate". This introduces another layer of complexity as the behavior of this external action needs to be understood. Lastly, the use of an additional secret token for the LLAMA_URL increases the risk and complexity associated with this change. Overall, this PR exhibits a high degree of potential for introducing bugs and requires a deep understanding of the project architecture and GitHub Actions best practices, hence it is categorized as 'BLACK'.
