How can I localise quotation marks with Biblatex?

Question

The default style of quotation marks in the Bibliography provided by biblatex is the US/UK style: “ ”. However, I would like to have the quotation marks in German style: „ “, but maintain my specified language (slovene).

Here is my MWE:

\documentclass[a4paper,12pt]{article}

\usepackage{filecontents}

\begin{filecontents}{bibliography.bib}
@article{article,
year = {2020},
number = {2},
author = {Someone Someone},
publisher = {Unknown University Press},
title = {The Title of the Article},
journal = {Studies of Something}
}
\end{filecontents}

\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usepackage[tmargin=1in,bmargin=1in,lmargin=1in,rmargin=1in]{geometry}

\usepackage[slovene]{babel}

\usepackage[backend=biber,style=authoryear,citestyle=numeric-comp]{biblatex}

\setlength{\parindent}{1cm}

\frenchspacing

\bibliography{bibliography}

\begin{document}

\section*{Section}

I want ,,this``, not ``this''. \cite{article}

\printbibliography

\end{document}

This will be done automatically, if you load babel (with, e.g., ngerman) and csquotes.

That is, remove your babel load and then add the following before your biblatex package load:

\usepackage[english, ngerman]{babel}
\usepackage[autostyle]{csquotes}

To additionally use this with other languages, lacking csquotes localization, simply ensure that the language containing the desired localization is loaded last. As requested in the comments, to also use slovene, load babel as follows instead, and its following csquotes invocation will then work as expected.

\usepackage[english, slovene, ngerman]{babel}

Alternatively, you can only provide your desired language and simply load csquotes as follows, manually specifying the quotation type:

\usepackage[slovene]{babel}
\usepackage[autostyle=false, style=german]{csquotes}
