pyscreeze 0.1.30 fails to execute properly on Ubuntu 22.04.

I have installed Pillow, but the following error persists. However, reverting to version 0.1.29 resolves the issue.

File "/test/.venv/lib/python3.10/site-packages/pyscreeze/__init__.py", line 628, in _screenshot_linux
    raise Exception(
Exception: To take screenshots, you must install Pillow version 9.2.0 or greater and gnome-screenshot by running `sudo apt install gnome-screenshot`
