Create documentation describing resources in Figma

[AetherUnbound]

Description

Originally reported by @sarayourfriend

Would it be useful to have a page in the Openverse documentation site that describes the resources in the Figma? The Figma could link to it? Or could that stuff be documented in Figma itself? A blurb about what each page of the Figma documentation is used for, where to find different resources, etc, would be helpful for getting oriented in it. The "what's this page" on the Utilities document is a good example of helpful information that could be on the other pages as well.
