bug#71849: pdflatex.fmt error using pandoc/pdflatex

[Antero Mejr]

When using pandoc to export markdown to PDF, the following error occurs:

```
kpathsea: Running mktexfmt pdflatex.fmt
mktexfmt: No such file or directory

kpathsea: Running mktexfmt pdflatex.fmt
mktexfmt: No such file or directory
Error producing PDF.
This is pdfTeX, Version 3.141592653-2.6-1.40.25 (TeX Live 2023/GNU Guix) (preloaded format=pdflatex)
 restricted \write18 enabled.
I can't find the format file `pdflatex.fmt'!
```

It appears that the texlive packages were refactored lately, so it is
difficult to tell what packages are needed. Currently the following
packages are installed:

texlive-base
texlive-bin
texlive-scripts
texlive-latex-base

Also I think the pandoc package should propagate the packages it needs
to build PDFs.

Could you please show us what command you used?  It's hard to work on
this when we can't easily reproduce the problem.

The command was:
```
pandoc -f markdown -t pdf -o out.pdf in.md
```

Any markdown file should reproduce the issue.

FWIW, I can export the following "in.md" Markdown file:

--8<---------------cut here---------------start------------->8---
# Titre de niveau 1
## Titre de niveau 2
### Titre de niveau 3

**Texte en gras**

*Texte en italique*

~~Texte barré~~

> Texte cité

- Liste à puces
- Avec plusieurs éléments

1. Liste numérotée
2. Avec plusieurs éléments

`Code en ligne`
--8<---------------cut here---------------end--------------->8---

using the command:

  guix shell --pure pandoc texlive-collection-latexrecommended texlive-ulem -- pandoc -f markdown -t pdf -o out.pdf in.md
