Render PDF docs

[Hofer-Julian]

Fixes #666

Blocked by conda-forge/quarto-feedstock#44

One option to make progress on this that @Hofer-Julian suggested is to remove quarto from our Pixi dependencies, and ask developers to install Quarto themselves again from https://quarto.org/docs/get-started/. We could keep using our Pixi tasks to build docs.

I'm afraid we cannot use Typst yet, it is currently only for individual documents: quarto-dev/quarto-cli#6979

But let's just push this forward towards decent PDF docs using Latex.

I keep running into errors. Using quarto 1.4 it cannot compile the title-block.md template, throwing an error similar to quarto-dev/quarto-cli#8556.

On quarto 1.5 prerelease I get:

ERROR:
compilation failed- error
Unable to load picture or PDF file 'index_files/figure-latex/mermaid-figure-1.png'.

Even though the file is there. This is the command I use to try to build the docs:

pixi run --environment=dev quarto render docs --profile manual --to pdf
