[Pulsar] Add Pulsar Badges for Stargazers & Downloads (#8767)

* Added pulsar-edit Downloads & Stargazers

* Manage colour similar to how Docker Badges do

* Fixed typo in colour

* Or it seems no other (not found) tests check colour, likely overrided elsewhere

* Remove usage of 'Edit'

* errorMessages => httpErrors && downloads => dt
