Bug 436951

SUMMARY
The guide for getting versions in the template for filing KDE bugs doesn't match Plasma desktop.

STEPS TO REPRODUCE
1. Enter a new bug, choose a product such as bugs.kde.org

OBSERVED RESULT
The bugzilla template includes
> SOFTWARE/OS VERSIONS
> Windows: 
> macOS: 
> Linux/KDE Plasma: 
> (available in About System)
> KDE Plasma Version: 
> KDE Frameworks Version: 
> Qt Version: 
but
a) it's not called "About System", it's called "System Information." Entering "About system" in the Plasma application launcher works, but it's a little confusing.
b) In Fedora 34, System Information does not display the KDE Plasma Version. Instead I run `plasmashell --version` in a terminal window.

EXPECTED RESULT
Better verbiage. Change to say something like "(available in System Information)", I'm not sure how to get Plasma version.

SOFTWARE/OS VERSIONS

Linux/KDE Plasma: 
(available in About System)
KDE Plasma Version: 5.21.5
KDE Frameworks Version: 5.81.0
Qt Version:  5.15.2 Wayland

ADDITIONAL INFORMATION
https://invent.kde.org/plasma/kinfocenter/-/blob/master/Modules/about-distro/src/PlasmaEntry.cpp suggests that it's trying to get the Plasma version from xessions/plasma.desktop, but comments
> // Since Plasma version detection isn't based on a library query it can fail
(I have /usr/share/wayland-sessions/plasma.desktop and /usr/share/xsessions/plasmax11.desktop ; I'll file a separate bug.)


Does this part of the bug template make sense for Windows and macOS users? Even without System Settings, they can still provide KDE versions; most KDE apps provide it in Help > About {KDE Appname} > Libraries. Or are the three lines intended to get the user to indicate which O.S. she is using, in which case collapse them to one question:

> SOFTWARE/OS VERSIONS
> Which O.S. (Windows/macOS/Linux) and version are you running? :
> The following are shown in System Information or a KDE application's Help > About {Appname} > Libraries.
> KDE Plasma Version: 
> KDE Frameworks Version: 
> Qt Version: 

Would it help to ask Linux users for Graphics Platform (wayland or X11) that my System Information shows?
