Describe your issue

Specifying a Luminosity, Density or Viscosity with a custom fluid does nothing - fluids do not glow with luminosity, there's no difference in flow rate or flow length.

evt.create("molten_diamond")
  .displayName("Molten Diamond")
  .luminosity(15) // Doesnt work
  .density(1) // Doesnt work
  .viscosity(10) // Doesnt work
  .stillTexture("kubejs:fluid/molten_diamond")
  .flowingTexture("kubejs:fluid/molten_diamond_flow")
  .color(0xAAFFFF)

Density and viscosity are forge-only fluid attributes with no actual effects despite being a number.

For the luminosity I think it might be a bug.
