Allow developers to test publish without actually publishing

One of the use cases for #58 is removing accidentally published extensions or extensions published as a test. If ovsx publish had a --pretend flag and the API had a corresponding parameter, this would allow developers to test publishing an extension without actually doing so.

In my case, I am publishing extensions via CI jobs (on GitHub this would be Actions). I accidentally published an invalid version of my extension because my CI script had a bug. If I could ovsx publish --pretend, I likely would have been able to work out all the bugs before making it live.

What would be the effect of --pretend?

I'm closing this issue, because it's stale. @firelizzard18 Please re-open this issue with an explanation of the intended effect of the --pre-tend flag.
