Incorrect airplane mode icon on plasma 6

[tkolo]

I'm testing Plasma 6 RC2 release and I've noticed that airplane mode icon is wrong (... right?):

I've asked around on #plasma:kde.org matrix channel and I've been pointed in direction of this blog post:
https://pointieststick.com/2023/08/12/how-all-this-icon-stuff-is-going-to-work-in-plasma-6/

For the sake of completeness, my relevant software/OS versions:
Arch Linux
Plasma version 5.93.0 (aka 6.0 RC2)
Arc theme version 20220908-2 (from official arch repositories)

The blog post say that Plasma 6 doesn't use the icons provided by the Plasma theme (arc-kde). Any wrong icon come from a wrong name or missing file in your global icon theme (papirus-icon-theme).
