ci: use builtin python action cache for pipenv (#796)

## 🔧 Problem

Python builds in Github actions seem to [fail randomly on Github
Actions](https://github.com/MTES-MCT/ecobalyse/actions/runs/11256209104/job/31297541397).

## 🍰 Solution

Try to use the now builtin [cache feature of the python github
action](https://github.com/actions/setup-python/blob/main/docs/advanced-usage.md#caching-packages)
to fix the problem.


## 🏝️ How to test
