Alpine Linux 3.20 was released recently [1]. As a result, the
`alpine:latest` image ref, that our Dockerfile uses, switched from the
3.19 to the 3.20 Alpine Linux release. This release has Python 3.12,
meaning that the following line in our Dockerfile now fails:
COPY --from=pymupdf-build /usr/lib/python3.11/site-packages/fitz/ /usr/lib/python3.11/site-packages/fitz
Bump the Python version in the Python system path to 3.12, so that we
can successfully build the container image.
