Use multi-color skin tone emoji

If in our docs we use any emoji with a skin tone (e.g. the 🙌 found in https://github.com/enhance-dev/enhance.dev/blob/9afb5739ed4f19605b50b75cf1c2e11fa2c58577/src/views/docs/md/learn/starter-project/pages.md#dynamic-if-need-be) I think we should replace that with some multi-color skin tone replacement; perhaps as an animation, or some other means.

There's a lot out there on this topic (Google: yellow skin tone emoji, etc.) and [some research](https://www.ed.ac.uk/news/2021/yellow-emojis-not-neutral-identity-symbols) relating to the inclusivity of defaulting to yellow.
