add customizable piglin trades

i would like to see customizable piglin trades, similar to how villagers have their own customizable trades.

heres an example on what the command could look like:

/summon piglin ~ ~1 ~ {barter:{id:iron_sword}

or maybe

/summon piglin ~ ~1 ~ {barter:{id:diamond},{id:netherite_ingot},{id:diamond_block{Count:5}}

maybe even a part in the command where you can make them passive even if you attack it, aren't wearing gold or open a chest, and it could look like this

/summon piglin ~ ~1 ~ {behavior:passive}

i wouldn't be upset if this wasn't added, i just think it would be  really cool!
