Updates a modifier group.
Each time a modifier group is updated, its revision increments by 1. The existing revision must be included when updating the modifier group. This ensures you're working with the latest modifier group information, and it prevents unintended overwrites.
This function requires elevated permissions and runs only on the backend and on dashboard pages.
