Use correct ${KF5_MIN_VERSION} variable to define minimum KF5 dependency versions for activities KCM
requested to merge aureliencouderc/plasma-desktop:fix-kf5-min-version-in-activities-kcm-cmakelists into master
The CMakeLists for the activities KCM uses a ${KF5_DEP_VERSION} variable for setting the required versions of KF5 dependencies but I couldn’t find this variable defined anywhere.
This patch uses ${KF5_MIN_VERSION} from the main CMakeLists instead.
