Update doc build instructions to ensure sufficient latex version
The instructions for setting up the environment for building the docs ( https://gitlab.com/inkscape/inkscape-docs/manuals/-/tree/master/Inkscape-Beginners-Guide ) can fail due to out of date latex version, and should be updated to clarify minimum system requirements.
Original issue description below:
The current sphinx build system fails when certain unicode characters are used, e.g., Ș
, which works fine in HTML, but fails to display in the PDF via LaTeX build, showing the error:
! Package inputenc Error: Unicode char \u8:Ș not set up for use with LaTeX.
Supposedly, this issue has been resolved in 2015: https://tex.stackexchange.com/questions/20182/how-to-use-unicode-characters-with-sphinx-rst-documents-and-properly-generate-pd
I've found some workarounds (on the LaTeX side) but using LaTeX macros instead of unicode means that the characters only show up in the LaTeX version, and not the HTML build.
