Evaluate if GL Project bots should keep owner role at group level

Due to the new restriction with GitLab permissions, bots must have owner permission at GitLab group level to perform some actions related to Gitlab runners management.

e.g the runner delete API: https://docs.gitlab.com/ee/api/runners.html#delete-a-runner-by-id

For group_type, you must have the Owner role in the target namespace. 

I think this is related to this code: https://gitlab.eclipse.org/eclipsefdn/it/webdev/eclipsefdn-vc-tools/-/blob/master/src/scripts/gl/GitlabSyncRunner.ts#L245
