Subject: [PATCH] Adds the ability to upgrade the material silos (#23142)

I forgot it in the original implementation. Now it is possible to
upgrade the components. It uses 3 matter bins and each tier provides 400
sheet storage.
so all level 1 bins gives 400, all level 2 gives 800 and all level 3
gives 1200.
