Elden Ring Locations - Altus Plateau

Every Altus Plateau item page, so the breadcrumb trail can tell one weapon class from another.

The class hubs file every page under all thirty weapon categories to fill the sidebar box, which leaves nothing in a page's categories saying what it actually is. This category is carried by item pages only, never by the hub, so an item reaches Elden Ring > Weapons > Altus Plateau while the hub stops at Weapons.

Hidden, and never added by hand: `tools/gen_item_pages.py` writes it.
