Cleanup cosign help text with a custom printer

[eddiezane]

Description

The output of cosign verify --help is unreadable due to line wrapping.

We solved this in kubectl by creating a custom tab printer.

Can I get this assigned? I want to try this :D

@hrittikhere are you still working on this? Otherwise, I would like to work on it :)

Hey @rnjudge I am actually trying a few iterations and should have something by this week. I will ping you if the results are not optimal so you can take over :)

A little bit more color: you could do this one of two ways.

The "right" way to do this is to send a PR upstream to Cobra addressing spf13/cobra#810 . This will be slower and take longer.

The easy way (probably what you should do first) is to basically copy kubernetes/kubernetes#104736 .
