Cleanup runner instructions project/group parameters

In !57524 (merged) we have removed programmatic access to the runner registration tokens. The same value is now returned by project_token, group_token and instance_token.

We should clean up those methods, which necessitates an update to the specs, and remove projectId and groupId from the graphQL query as those parameters are not used. Finally, we should update the frontend component to support the new graphQL query and cleanup the project/group parameters there as well.
