Subject: [PATCH] pretix: fix pretix-manage runserver by using makeWrapper
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

I noticed that running pretix runserver does not work:

% nix run .#pretix -- runserver localhost:8001
  File "/nix/store/ack7nv8s8g5lcmypr9ayb5291n0yk4ad-pretix-2025.5.0/bin/pretix-manage", line 2
    PATH=${PATH:+':'$PATH':'}
         ^
SyntaxError: invalid syntax

I don’t know exactly how or why I get a Python error when
bin/pretix-manage clearly has a Bash shebang, but I looked
at other django web apps in nixpkgs and noticed that they
were using a different way to create the manage.py wrapper.
And indeed, when using makeWrapper, runserver starts working.
