There isn't a space between the "Scope" paragraph and "Ethical Guidelines", here: https://huggingface.co/docs/diffusers/main/en/conceptual/ethical_guidelines , yet I can't see that in the preview. In this PR, I'm simply adding some spaces in the hopes that it resolves the issue.....

* add ethical guidelines

* update file name

* edit file name

* update toctree

* Update docs/source/en/conceptual/ethical_guidelines.mdx

* Update docs/source/en/conceptual/ethical_guidelines.mdx
