Update the zsh completions
Created by: evelikov
At the moment the zsh completions are more complex than they need to, clumped into a single file and ultimately very outdated. This PR fixed all of those.
Note that the -h
and --help
handling is a bit bonkers - some tools only honour the former, while others handle both ... but only if they are the first argument. Fixing that will happen with another PR.
