SUMMARY
Using the F1 to open the help page for some programs, opens a old KDE Docs page, like this one https://docs.kde.org/index.php?branch=stable5&application=kfind&path=index.html or https://docs.kde.org/index.php?branch=stable5&language=pt_BR&application=spectacle&path=index.html and etc, I think every program from KDE that has the ability to open the online help page is redirecting to this old KDE Docs

STEPS TO REPRODUCE
1. Update to Plasma 6.5.90
2. Open any KDE Plasma application (like Ark, Dolphin, Gwenview and etc, except for Krita and Kdenlive)
3. See the site

OBSERVED RESULT
Pressing F1 or clicking in the man button goes to the old KDE Docs page

EXPECTED RESULT
Pressing these buttons should open the newer handbook page like this https://docs.kde.org/stable_kf6/en/kfind/kfind/index.html or https://docs.kde.org/stable_kf6/pt_BR/spectacle/spectacle/index.html

Linux/KDE Plasma: 6.18.5-arch1-1 Wayland

ADDITIONAL INFORMATION
I think before updating to the 6.6 beta it was working fine, but I'm not 100% sure, my system is also on PTBR language (pt_BR.UTF-8)
