api/web/task-groups/{TaskGroupId}
Updates an existing task group. Only the Name can be updated.
The ParentId of the model is ignored: because it is an optional
field, honouring it would silently move a group to the top level
whenever a caller omits it from the request body. Use the
MoveTaskGroup endpoint to change the parent of a task group.
