Fix special characters in PDF version of User Guide

Overview

Hello! This commit solves the linked issue. Though here are some things that I wanted to point out.

I had to point to the fonts directory at the documentation.gradle.kts file because I was getting errors saying that
GEM_FONTS_DIR was not found.

After update, I had to download the default fonts from https://github.com/asciidoctor/asciidoctor-pdf/tree/master/data/fonts

I also changed the "rare" Japanese charset, U+FF0 emoji.

Here: https://github.com/asciidoctor/asciidoctor-pdf/blob/v1.5.x/docs/theming-guide.adoc#applying-your-theme it says that one can do pdf-fontsdir="path/to/fonts;GEM_FONTS_DIR" yet it did not worked.

Yet this commit solves the emoji problem.

Thanks! I'd like to avoid copying the fonts. Let's see if we can get @mojavelinux to chime in on #2315 (comment). 🙇‍♂️

You definitely should not have to copy the fonts. I'll have a look and see if I can detect what is going wrong.

I left a comment at #2315 (comment) and the issue should be fixed now but thank you @marcphilipp and @mojavelinux again for the help 😄
