Don't specify python patch version for pipenv
The base container image is `python:3.7-alpine`, but pipenv was
instructed to install packages for python 3.7.3. While this worked, as
soon as a newer patch version would be released the build would fail.
Thus, now pipenv will use any python 3.7 patch version that is
available.
