System Settings example

SUMMARY
After Plasma 6 upgrade, most of the new features that were added or reworked lost their correct localization.
All relevant localization packages (i10n) are installed correctly and fully updated.

After checking at - https://l10n.kde.org/stats/gui/stable-kf6/team/pt/ - I can see that there are in fact many missing translations for KDE 6. So this report is more of a reminder or "ping" to try and reach someone who can maybe help solve this, or maybe even ping/notify the pt_PT translation team.

Many critical parts of the system are not localized now on Plasma 6. This does not only affect some obscure menus, but most importantly affects very forward facing menus, settings and descriptions. Stuff like main "1st level" menus in the system settings are not localized at all, and/or there is a serious mix of English and Portuguese.

This affects specifically the European Portuguese locale (pt_PT or only "pt"). I have not tested the pt_BR (Brazilian Portuguese) locale.

I  will add in the attachments section some screenshots with annotations to serve as quick examples.

This might also be important for this report, I don't know if this might have triggered any bug related to these missing localizations or not, but I will just link it anyway: https://mail.kde.org/pipermail/kde-i18n-doc/2023-January/001340.html


OBSERVED RESULT
Mixed of English and Portuguese localization all throughout the desktop and many of the KDE applications.

EXPECTED RESULT
As close as possible to "everything" being correctly localized to the chosen language (in this case, pt_PT).
