[texdoc] `etoc` package: German translation in first place

[Denis Bitouzé]

Hi,

the locale of my computer is fr_FR.UTF-8. Nevertheless, here is the
output of `texdoc -l etoc`:

  ┌────
  │ 1 /home/bitouze/texlive/2022/texmf-dist/doc/latex/etoc/etoc-DE.pdf
  │   = [de] Package documentation
  │ 2 /home/bitouze/texlive/2022/texmf-dist/doc/latex/etoc/etoc.pdf
  │   = Package documentation
  │ 3 /home/bitouze/texlive/2022/texmf-dist/doc/latex/etoc/README.md
  │   = Readme
  └────
 
The German translation of the documentation shouldn't be the first one.

All the best.
