For use in the keystone docs site, these are being removed from the repo as storing images in a repo is unideal
Assets here are synced to S3 and then can be accessed at https://keystonejs.s3.amazonaws.com/framework-assets/
For example, accessing assets/admin-ui.png, you can use the link https://keystonejs.s3.amazonaws.com/framework-assets/assets/admin-ui.png
