deskutils/kodaskanna: update to 0.2.2, latest upstream, and Qt6
Kodaskanna is a utility for reading data from 1D/2D codes (e.g. QR codes or
bar codes) and making the data available for further processing. This port-
update catches 3 years of upstream activity and switches the toolkit
to the current Qt version.
