[Bug] Gem of Eternal Density doesn't respect actual hotbar size

[programmerjake]

Describe the bug
Using dreambuilder_hotbar and other similar mods, you can set the hotbar to any size you please. Gem of Eternal Density has hardcoded values instead of using player:hud_get_hotbar_itemcount()

Expected behavior
use player:hud_get_hotbar_itemcount() to get the correct hotbar size.

Game (e.g. Minetest Game)
Minetest Game
