ImageGrab.grab() Fails to detect that I'm on Wayland

[Desyncfy]

What did you do?

I used ImageGrab.grab() on Hyprland.

What did you expect to happen?

Auto-detect that I was using Wayland with grim installed and attempt to take a screenshot with that.

What actually happened?

Attempted to use an X11 function to grab the screen instead. (Image.core.grabscreen_x11(display_name))
Error:

❯ python3 piltest.py
Traceback (most recent call last):

# Run on Hyprland
from PIL import ImageGrab

ImageGrab.grab()

#8912 added support for Grim, but that was only released with Pillow 11.3.0.

Would you be able to upgrade Pillow and try again?
