Currently the plasmoid is still written for KF5/Plasma 5, and in addition
it also still uses PlasmaComponents2 stuff, which has been removed in
KF6/Plasma 6. So, this is an attempt to port the plasmoid so that it works
in Plasma 6.
BUG: 476389
The percentage sign in strings like ‘%1% charging’ couldn’t
be properly translated in the resulting POT file. For example,
translating it to ‘%1 % charging’ (some languages use a space
before the percentage sign) resulted in an invalid Java printf
string (but a valid QML string), which was reject by msgfmt.
