Updated visuals for characters

Judging by how the visuals of Sunflower and Wall-Nut have been transitioned from 2.5D to almost full 2D to make them fit more with the current visual style PvZ3 is going for, Certain characters (Plants and Zombies) need remakes to fit with other things, because alot of stuff really sticks out up close in the almanac. (BELOW ARE SOME EXAMPLES)

Diggin' Zombie (2026)

Typical appearance of Bowling Zombie (since 2021 or 2022)

Note how Bowling Zombie has more 3D shoes that are fully modeled. Meanwhile Diggin' Zombie is fully 2D.

This would be great for optimization purposes (for obvious reasons) But will visually improve how certain things look now that zombie bases exist properly
