babel naustrian is not detected as austrian german

[456Xander]

Describe the bug When using LaTeX and babel, the language should be detected automatically. Using babel with ngerman, the language is correctly detected as de-DE. However, when writing documents in austrian German (babel naustrian), the language gets wrongly detected as en-US. The detected language should be de-AT.

Steps to reproduce Create a Latex document and use

\usepackage[naustrian]{babel}

Expected behavior Language gets detected as de-AT.

Sample document

```latex \usepackage[naustrian]{babel} \documentclass[a4paper]{scrartcl} \begin{document} Das ist ein korrekter Satz. \end{document} ```
