pt_BR translations not loaded

Hi,

Recently pt_BR was added to several branches (5.12, 5.15, 6.0 to 6.2 and dev) and I tested on Linux (KDE) but pt_BR translations were not loaded, instead the pt (pt_PT) 11 years old partial translation were loaded as seen on the attached screnshot.

The 8 first strings come from Qt and we can see that only one is translated (Limpar -> Clear). That was the hint to find the problem, it came from qt_pt.ts (.qm compiled)

I should have loaded qt_pt_BR.ts instead.

Regards
