Alpine ships uWSGI linked against the most recent Python version,
i. e. currently python3.9. The current deployment uses python3.8
though, so whenever our Python version diverges from Alpine's
stable version, uWSGI will break (aka fail to run the parser).
Switching to installing uWSGI via pip into the pipenv will make sure
that the uWSGI Python module's version will always fit our venv.
