command/upgrade: can't disable spinner

[johnstonmatt]

I'm looking to disable the spinner that runs during an upgrade operation, but I can't figure it out. Is there a bug in the module, or am I doing something wrong?

I've tried a number of things, my upgrade provider for GitHub releases is the context in which I'm hoping to supply my own spinner instead: https://github.com/polyseam/cliffy-provider-gh-releases

Thanks!
