Download count badges for packages hosted on the GitHub Package Registry

- Which service is this badge for e.g: GitHub Package Registry
- What sort of information should this badge show? Package versions/latest version


:link: **Data**

- Is there a public API? Yes
- Does the API requires an API key? Auth should be used like our other GH services, specifically leveraging our [BaseGraphQlService](https://github.com/badges/shields/blob/master/core/base-service/base-graphql.js).

:microphone: **Motivation**
Because people want them! 😄 The motivation/benefits for the version badges for the GH Package registry is the same as the other registries we support
