binder: Install packages required for Jupyter to PDF convert

Per jupyter/nbconvert#1328, these
are the packages needed for Jupyter to be able to convert
to PDF. Without it, you get unfriendly errors like [this]
(2i2c-org/infrastructure#3188 (comment)).

Given that the binder image includes jupyter, and texlive is included
in the base, I hope it would be reasonable for the binder image
to include enough texlive packages for PDF conversion to work.
Otherwise, it works in RStudio but not in Jupyter.
