GlobalMenu: Fix path to AboutPage.qml
This PR fixes the About Page not opening from the Global Menu.
The GlobalMenu seems to prefix the AboutPage with qrc:/
, and this is preventing the About Page from opening from the Global Menu when going to "Help -> About System Monitor". There is no crash, it simply does not open.
This PR fixes this by removing the qrc
prefix, making the path consistent with that of `Main.qml`: https://invent.kde.org/eamonnrea/plasma-systemmonitor/-/blob/a5c753aa03d1b62364e330399a07dcd15be84414/src/Main.qml#L126
I am not sure what the qrc:/
prefix is about, but no other paths seem to use it. Looking at the commit history it seems like this may have been not working for a while, but not sure :-)
Thanks!
