Set DAWN_FORGE RecipeModifier to be the weak steam parallel one

[jurrejelle]

Means you can't run MV+ recipes anymore in the steam dawn_forge

It used to no t do anything since the dawn forge isn't an electric machine so the previous recipemodifier was a no-op
in

(machine, recipe) -> {
                if (!(machine instanceof IOverclockMachine overclockMachine)) return ModifierFunction.IDENTITY;
                if (RecipeHelper.getRecipeEUtTier(recipe) > overclockMachine.getMaxOverclockTier()) {
                    return ModifierFunction.NULL;
                }
                return logic.getModifier(machine, recipe, overclockMachine.getOverclockVoltage());
            })

it'd fail the first IOverclockMachine check

This PR also limits the tier to LV, since all Steam Multis have that limitation built into their modifier.

Before: (Running HV recipe)

After (doesn't run)

Woah another PR, lgtm!
