remove remaining cz files and dependencies

[bmuenzenmeyer]

Description

missed these somehow during #7317 - but it's always confusing to me looking at the cz.json file in our top-level directory

added benefit of removing a huge chunk of dependencies - but i didn't bother measuring impact

Validation

everything should still work
