Akira Yokosawa 1e596d5eff docs: Detect variable fonts and suggest denylisting them
Fedora and openSUSE has started deploying "variable font" [1] format
Noto CJK fonts [2, 3].  "CJK" here stands for "Chinese, Japanese,
and Korean".

Unfortunately, XeTeX/XeLaTeX doesn't understand those fonts for
historical reasons and builds of translations.pdf end up in errors
if such fonts are present on the build host.

To help developers work around the issue, add a script to check the
presence of "variable font" Noto CJK fonts and to emit suggestions.
The script is invoked in the error path of "make pdfdocs" so that the
suggestions are made only when a PDF build actually fails.

The first suggestion is to denylist those "variable font" files by
activating a per-user and command-local fontconfig setting.

For further info and backgrounds, please refer to the header comment
of scripts/check-variable-font.sh newly added in this commit.
