For Ubuntu/Debian, building PDF documentations needs four texlive packages.
See https://www.sphinx-doc.org/en/master/usage/builders/index.html#sphinx.builders.latex.LaTeXBuilder.
For RHEL/CentOS/Fedora, building PDF documentations needs python-sphinx-latex or python3-sphinx-latex.
Separate the "install dependencies" instructions for RHEL/CentOS and
Fedora into two sections, due to the differences of some package names
and the prefered package manager (yum/dnf).
