Add update script for new klipper clear dialog config
Previously, Klipper "clear history" dialog used to not ask again even if user answered No.
This was changed so that only a Yes answer will lead to no more asking, by using warningContinueCancel
instead of questionYesNo
.
Now the behaviour of previous config value really_clear_history
has inverted: true/undefined => ask again; false => don't ask.
This update script migrates old configs to use the new config value, renamed to klipperClearHistoryAskAgain
.
Depends on plasma-workspace!816 (merged).
