Remove accessories category

### What Happened?

Currently developers are using accessories like a junk drawer instead of actually adding categories for their app. This gives this impression that categories are empty, even though apps exist that should be present in them

### Steps to Reproduce

Open Accessories and see all the apps. Open categories and see far fewer apps

### Expected Behavior

Apps should use proper categories instead of accessories. To incentivize this, we should remove the accessories category
