Subject: [PATCH 20/24] Use a more reasonable fallback directory for fonts on
Windows
The existing fallback points to a directory that no longer exists by default
which causes warnings like the following on run-time:
```
QFontDatabase: Cannot find font directory C:/msys64/mingw64/qt6/libs/fonts.
Note that Qt no longer ships fonts. Deploy some (from
https://dejavu-fonts.github.io/ for example) or switch to fontconfig.
```
From MINGW-packages commit 6fa4cbd657c7853d664247636675192be74b281d.
