Add compatibility with django 5.0

[DeeeeLAN]

Environment
django-ptpython version: v1.0.2
django version: v5.0.6
python version: v3.12.3
pip version: v24.0
os: python:3.12.3-bookworm

Describe the bug
Attempting to install the listed versions above shows a dependency error, stating django-ptpython requires django<4.0.0,>=3.2.14.

[DeeeeLAN]

Installing v1.0.1 allows django<5.0,>=4.0, which still doesn't help.
