plz fix the bug in Celestial Scion

In SGalterguardian_phase4.lua

local function SetPreventDeath(inst, prevent)
	inst.components.health:SetMinHealth(
		prevent and
		not inst.components.health:IsDead() and
		math.min(1, inst.components.health.currenthealth) or
		nil
	)
end

This function sets minhealth to nil instead of 0.

I'm aware there are nil checks in the official code,

but many mods don't include them since the value has consistently been a numeric type for years.

This has already caused multiple mods to crash, such as ShowMe.

A simple change (replacing nil with 0) would resolve this — please consider it, Klei!
