Lack of kf5 branch leads to kdesrc-build and API docs generation issues
KColorScheme is in the frameworks group, where most projects have a kf5
branch that is used by kdesrc-build and the API docs generation script (python3 ../repo-metadata/git-helpers/git-kclone frameworks/* --branch=kf5).
KColorScheme lacks a kf5 branch, so both tools fail.
