* Fix plate shard variants never appearing (and slight tweaks) (#84227)
## About The Pull Request
Using `pick` instead of `rand` = only two variants showed up, the first
or the last. Easy fix.
While I'm here I made them a bit more "immersive" I guess, better
hitsound (they're sharp!), caltrop sound, and reduced the stun from
default (6 seconds) to 2 seconds
## Changelog

fix: Fixed plate shards not randomizing icon correctly
qol: Gives plate sharts a more fitting hitsound / caltrop sound, gives
them a set caltrop stun duration (instead of default)
