Add new Sponsor image to the styleguide: <img width="344" alt="SponosoredByFastRubyLogo" src="https://user-images.githubusercontent.com/7442887/140193742-f9bca245-4269-4782-ad6d-73a6604bc556.png"> (We use this image in the README file of all our OSS repos) I think this can go in the Logo section or maybe in a new section. ___ Jira ticket with the original assets (PNG/SVG): [UXD-45](https://ombulabs.atlassian.net/browse/UXD-45)
