PUT /v1/oidc/group specifies .uuid as required

### Current Behavior

The API docs show .uuid as required for creating a group, when in reality it's the name that is required and uuid will be ignored. Name is not marked as required.

### Expected Behavior

.uuid is not present at all
.name is marked as required
