This pull-request makes a few changes to our `<Badge />` component to
bring it inline with Figma.
* Added all variants to the stories of Figma (they can vary per
badge-type, so its better we track everything).
* Removed the `border` variant of the component, border variants should
be on all `sm` and `md`.
* Added a hover effect to the `default` variant (per-design).
* Resolved issue with sizings of `xs` and `sm` plus resolved
iconography.
* Resolved issue with icons not showing at all on `xs` variants.
