[Builds] Remove elements unnecessary with the new version-bump workflow

With the new reusable workflow for automated version increments in
pull-requests it is not necessary anymore to bump versions in advance
during release preparation or the enable bumping if the property
'compare-version-with-baselines.skip' is set to false.
Everything now happens automatically and these elements can therefore be
removed.
