[bug#55644] [PATCH] gnu: Add texlive-qrcode.

[Jack Hill]

* gnu/packages/tex.scm (texlive-qrcode): New variable.
---

This is my first texlive package, so hopefully I got it at least
somewhat right. It is based heavily on the texlive-makecmds package. I
determined the native-inputs by what was required to build qrcode.pdf
and the propagated inputs by what was required to build this test
document:

```

\documentclass{article}

\usepackage{qrcode}

\begin{document}

\qrcode{test text}
\end{document}
```
