Made PRs for 1.21 and 1.20.1 to add #pmmo:magic damage type to damage_dealt events.

Also adds Iron's Spellbooks damage types to #pmmo:magic tag.

• [1.20.1] #568
• [1.21] #569

A note: I followed the existing layouts for the java file, but I don't have a dev environment and haven't tested those. Please double-check them if you can.

One thing it is lacking is how to boost damage/mana with it.

Is there a way to make a perk like this apply to all of one damage type? Or can applies_to do that?

		[[Perks.For_Event.DEAL_DAMAGE]]
			applies_to = ["ars_nouveau:spell_bow"]
			skill = "magic"
			perk = "pmmo:damage_boost"

Made feature request: #571

Will set both of these PRs to draft until this is resolved one way or another.
