system-requirements.rst: add dependencies for pdf builds

With the recent changes from commit
bd6265ca323fac547a197bb516dc4a9ef3897508 ("doc: Makefile: add support
for xelatex"), the list of dependencies needs to be updated.

The initial list of dependencies was made for Ubuntu/Debian, and the
packages were translated for the other distros using pkgs.org.

Add them separately from the rest of the dependencies as they pull a
_lot_ of additional dependencies (for LaTeX).

Move the texlive-fncychap documentation dependency to the PDF specific
dependency.

Notes:
- Fedora/OpenSUSE do not have the "lang-all" texlive collection, so
  install all available languages.
- AlmaLinux does not seem to provide texlive-collection-fontsextra,
  texlive-collection-lang*, and texlive-collection-latexextra, so add a
  warning about that.
