fix: pandoc requires texlive to render latex in notebook

The new notebook has some latex insets, and I believe pandoc is
generating empty environments for them, which translate into warnings
assumed as errors.

It is the only difference I could think of between the environment in
CircleCI and the testing environment I've created on my workstation.

Resolves: #414.
