[shipwright-admin] Adding new admin to Admin Team

Hi all, I would like to request adding Sascha Schwarze to the https://github.com/orgs/shipwright-io/teams/admins team. This is needed as he have lots of context in the project and sometimes we need to perform admin tasks where only myself is able to do them. Do you mind if I add him to the admins team? Regards, Enrique E. Encalada
