Remove all the scaffolding in our `build-image.py` script for using the `poetry.lock` file, now that we install PyMuPDF from the Debian repos.

|
# becomes an issue when we want to vendor the PyMuPDF package, using `pip`. In order
|
|
# to sidestep this virtual limitation, we can just change the Python version in the
|
|
# generated `requirements.txt` file in Ubuntu Focal from 3.9 to 3.8.
