Make Baklava Pie retain its quality after slicing (#88118)

## About The Pull Request

Adds the crafting complexity to the slices of baklava, so it doesn't go
from very good to nice after you slice it.
Was asked to put the fix to upstream.

## Why It's Good For The Game

If I have one more food suddenly degrade in quality after slicing it
into multiple portions I am going to explode the fucking kitchen,
especially after having to bother Hydroponics to mutate a plant
specifically for it
