Add shuriken variants

[Arcanorum]

Task description

There is currently only 1 type of shuriken in the game, just called "Shuriken".
This weapon is crafted from iron bars, which implicitly makes it part of the iron tier of weapons, even though there are no shurikens made of other metal types.

The current shuriken should be renamed to "Iron shruiken" and new shurken items should be added for dungium, agonite and noctis metal tiers.

References/notes

New assets should be drawn using the dungeonz colour palette:

This would need a huge nerf on iron shurikens, cuz it does the same damage as a noctis arrow rn

Maybe not a huge one, as they have much shorter range.
