Removes Plasmeme innate damage vulnerability, replaces it with demolition vulnerability (#94328)

## About The Pull Request

Splinter of #94324

Plasmamen no longer take 1.5x brute and burn damgae
Plasmamen are now affected by demolition modifier, meaning they take
less damage from sharp objects and more damage from blunt objects

Skeletons and golems are also affected by demolition modifier

## Why It's Good For The Game

As a part of #94324 I was making `MINERAL` mobs affected by demo mod
But I realized this would absolutely murder the heck out of Plasmamen!
1.5x brute + another 1.25x brute from blunt objects!
But then I realized "wait that kinda makes sense... a lot *more* sense
than the arbitrary damage modifier"
So here we are

Plasmemes are as vulnerable to being smashed to bits as before, but can
now boast a minor resistance to being stabbed due to their lack of
fleshy bits

This feels a bit more appropriate to their skeletal nature without
completely removing that aspect of their character. It also gives them a
very minor upside (they need it)

## Changelog

🆑 Melbert
balance: Plasmamen no longer take flat 1.5x brute and burn damage
balance: Plasmamen are now affected by weapon demolition modifier,
meaning blunt attacks deal more damage but slashing or piercing deal
less damage
balance: Skeletons and Golems are also affected by weapon demolition
modifier, as well as any mineral type mobs (of which none currently
exist)
