Allow villagers to eat simple vegetables

[isErenG]

Villagers weren't able to consume some of the items they picked up (cabbage, tomatoe, rice, onion). Created a simple mixin to modify the FOOD_POINTS map.

I didn't give much thought to the food point worth so feel free to change it accordingly. I think it is fine though.

It's not up to me to pull this or not but Farmer's Delight uses the following code along with accesstransformers to modify hard coded collections, so this implementation wouldn't be consistent with the rest of the mod. https://github.com/vectorwing/FarmersDelight/blob/afc79de755ae04d20ed9654ab4056e53a717cf32/src/main/java/vectorwing/farmersdelight/common/CommonSetup.java#L119-L142

I saw this file but the FOOD_POINTS map is immutable in Villager.class. That's why I resorted to making a mixin instead.

the private and final modifiers can be changed using the accesstransformer file https://github.com/vectorwing/FarmersDelight/blob/afc79de755ae04d20ed9654ab4056e53a717cf32/src/main/resources/META-INF/accesstransformer.cfg#L5-L8

Oh I didn't know, I'll rewrite it then. Tysm
