Update martialart_json.md

Is your feature request related to a problem? Please describe.

Some properties used in the martial_art type are not documented.

Describe the solution you'd like

Document the following properties:
primary_skill
strictly_melee
arm_block_with_bio_armor_arms
arm_block_with_bio_armor_legs
force_unarmed
ongethit_buffs

The static_buffs is noted as an array but then continues to use keys as values, as though it was an object. Should be fixed by adding { at the start and } at the end of the key/value pairs

leg_block refers to arms instead of legs in its description

Describe alternatives you've considered

knockback_follow claims to use an int, game asks for a bool.
