[WIP] starting to add figma to new docs

This is the very beginning of adding figma to the new docs.

👀 Preview

Changes

• removes figmaUrl and replaced with figmaId
• store figma data in graphQL
• provide data to components through props

Todo

• currently data is loaded in the components from an npm module, this should be replaced so that it is available via gatsby @josepmartins @danielguillan can you do this?
• currently component.thumbnails.prop is an object with dynamic props. We should replace this with an array of entries ['propertyName', 'propertyValue'] so that it is graphQL compatible @danielguillan @josepmartins
• some components, like actionList are not available. I think this may be, because it is not a component set CC: @danielguillan?
• Pictures don't show up, this is either figma and they are gone, or an issue with access rights / cors, etc. @colebemis any idea?
• individual properties should be added automatically, we need to have a list of all properties in gatsby to loop over the props and add the components.
• somehow the anchor nav does not show up
• fix inconsistent spacing below headlines
• images don't show up
• we should probably remove the last edited by section in the overview, right?
• spacing in overview (to section below yellow note) should be adjusted to fit to react page
• components should be cleaned up and named better.
