Fix Medieval Stuff martial style traits

Summary

SUMMARY: Mods "Fix Medieval Stuff martial style traits."

Purpose of change

Fixes #27899.
Fixes #27831.

Describe the solution

Martial arts traits defined in the Medieval Stuff mod were overriding the base traits instead of adding to them.

Quoting @chaosvolt on why this happened.

For the longest time it would automatically append the added martial art to the list of styles. Back when I first added it I tried a full override and it populated the martial arts list with duplicate entries for the styles that were on the list in vanilla, but it worked when I used the method you've seen here. Seems that behavior's changed at some point.

Is there no "append" syntax to allow multiple martial arts mods?

@ifreund Could you also change the Melee Weapon Training trait to add Niten Ichi-Ryu and Sojutsu in the description? That one little thing is bothering me since Niten was added to the trait lol

On it, must have read too fast when I was reading through your issue.
