The reusable workflows fem-on-kaggle/open-in-kaggle-workflow/.github/workflows/workflow_call.yml@main and fem-on-colab/open-in-colab-workflow/.github/workflows/workflow_call.yml@main are not allowed in multiphenics/multiphenics.github.io because all reusable workflows must be from a repository owned by multiphenics or match one of the patterns: RBniCS/check-jupyter-metadata-action@*, fem-on-colab/warn-workflow-about-to-be-disabled-action@*.
