Create a GraphQL query for contributed projects
Background
For &13066 we want a way to show projects that users have contributed to in the Contributed
tab. We already have GET /users/:user_id/contributed_projects
but for API parity we should try make this data available via GraphQL as well. See discussion in #446241
Implementation guide
Add a new Query.user.contributedProjects
GraphQL query by adding a new field contributed_projects
similar to starred_projects in UserInterface
and use the ContributedProjectsFinder
to get the contributed projects. Add a sort arg to the resolver and make latest_activity_desc
its default value.
