"apk upgrade -a" should reset versioned world dependencies

Doing “apk add file.apk” adds a versioned dependency to allow downgrading, and sticky version. Most often this is to install single packages from newer repository. So it would make sense to reset them to non-versioned if doing “apk upgrade -a”.

upgrade: reset versioned deps in world when doing upgrade -a

Doing "apk add file.apk" adds a versioned dependency to allow
downgrading, and sticky version. Most often this is to install
single packages from newer repository. So it would make sense
to reset them to non-versioned if doing:

 apk upgrade -a
