New RBAC role needs client changes to grant permission #2183

Hi team, I have created a new RBAC role in Weaviate (read_backups) as of 1.39, in this PR: weaviate/weaviate#13433

It needs changes to the client to understand and assign the permissions. Please can you incorporate it into the client? I have added the needs-mirror label so that it is duplicated to all the other client repos.
