Debian 12 changed how pip works

[crowtrobot]

In Debian 12 (and I think some other Linux distributions) changes were made to the way pip works to discourage installing things in a way that might conflict with the versions installed by apt-get. AFAIK (and I am not an expert, so feel free to correct me) you now have to create a python virtual environment, have pip install the packages there, and then run your program from that virtual environment so it can see the packages.

I just finished re-installing my Seafile Server on a Debian 12 VM using a python venv, and so far it seems to work. I made some notes on what I had to do different from the steps in the manual. The differences are pretty small. Just make the venv, activate it before running pip, and made a script to start the seahub and seafile scripts with the venv. I will submit a pull request with edits to the relevant sections.

I've never done this before, so please tell me if I've done anything wrong.
