Enhanced documentation / visibility around registry related errors

Hey!

I have been struggling for a couple of hours in order to release a new version of a provider I maintain: https://registry.terraform.io/providers/mvisonneau/updown/latest

I found it very difficult to troubleshoot this error and was wondering if there was an opportunity to be a bit more explicit or transparent about what the error actually is.

On top of this, if anyone has any idea what is wrong with my setup as it still does not work. I would love to get some help on this! :bowing_man:

Cheers,
Maxime
