[CR] Updates martialarts_json.md doc

[Mooses2k]

Summary

SUMMARY: Infrastructure "Updates martialarts_json.md doc"

Purpose of change

It was out of date and I just worked on some martial arts code, so I thought I'd improve it.

Describe the solution

Went through techniques.json and martialarts.json, put in everything I could think of that might help.

BE AWARE, knockback_follow references #30668 which is not yet merged.

Describe alternatives you've considered

Doing nothing, but that's not very helpful.

Additional context

"Weighting" and "Defensive" - somebody chime in on these, please

[Hymore246]

Defensive - Used by the game to automatically exclude a technique from being randomly selected to use when attacking.

Weighting - Effects how likely the technique will be randomly selected when attacking. The number indicates how many extra "copies" are added to the technique pool when doing a random pick. This can be negative value which will reduce the chance of of the tech triggering.

AoE - Both Wide and Spin have extra checks in the code before they can be picked and used. Spin requires at least 2 hostile creatures to be adjacent to the player in order to be a valid pick. Wide requires at least 2 hostile creatures to be adjacent to the player and the attacked target must have another creature adjacent to it. In other words, AoE techs CANNOT trigger against solo targets.

Thanks. Changes made. It's all ready, in my eyes.
