Maintenance of [packaging] module

Module to maintain

Website: https://school.brainhackmtl.org/modules/packaging/

Code: https://github.com/school-brainhack/school-brainhack.github.io/tree/main/content/en/modules/packaging

Work to be done

The Python packaging ecosystem has significantly evolved since this module content was originally developed. To ease maintenance burden and to better reflect current state-of-the-art, I would propose that the material should focus on the official Python packaging tutorial : https://packaging.python.org/en/latest/tutorials/packaging-projects/

I would also suggest that this tutorial could have more direct links with the testing module, as both the official tutorial and other, updated resources include testing in their initial package definition.

检查 content/en/modules/packaging 中的模块内容，并将其与 issue 中链接的官方 Python packaging 教程进行比较。检查现有的 testing 模块和所引用的 packaging 注释，确认其中的相关联系。完成的标准是 packaging 材料反映当前的指导内容，并清晰地链接到 testing 资源。
