Gunmod parameter "ups_charges" mentioned in documentation but ignored by the game.

Describe the bug

I'm trying do define a gunmod that adds UPS power consumption to the weapon that hasn't it in stock condition. That doesn't work despite being documented in JSON_INFO.md

Steps To Reproduce

Steps to reproduce the behavior:

1. Define given gunmod:

  {
    "id": "electric_pump",
    "type": "GUNMOD",
    "name": { "str":"electric pump", "str_pl":"electric pumps" },
    "description": "A high pressure electric pump, greatly decreases pneumatic weapon reload time, but requires UPS charges to work.",
    "weight": "120 g",
    "volume": "250 ml",
    "integral_volume": 0,
    "integral_weight": 0,
    "price": 1500,
    "material": [ "steel" ],
    "symbol": ":",
    "color": "dark_gray",
    "location": "mechanism",
    "mod_targets": [ "tihar", "helsing", "pneumatic_shotgun", "airspeargun" ],
    "install_time": "30 m",
    "min_skills": [ [ "electronics", 4 ], [ "mechanics", 3 ] ],
    "ups_charges": 5,
    "reload_modifier": -95
  }

2. Spawn pneumatic rifle and attach gunmod.
3. Check if it requires UPS charges to shoot.

Expected behavior

Gun starts to require specified amount of UPS charges to shoot.
