Remove deprecated devicePixelRatio related code
kirigami::Units::devicePixelRatio() has been deprecated so it needs to be removed.
As kirigami documentation explains: "since 5.86. When using Qt's high DPI scaling, all sizes are considered to be device-independent pixels, so this will simply return 1."
