Pull Request Overview

This PR corrects the login prompt for the jozu.ml registry by changing the username prompt to "Email:" instead of "Username:" when logging into jozu.ml specifically.

• Updates the username prompt to "Email:" when the registry is "jozu.ml"
• Maintains backward compatibility by keeping "Username:" for all other registries

Hard-coding the registry name "jozu.ml" creates a magic string that could be error-prone. Consider defining this as a constant (e.g., const JozuMLRegistry = "jozu.ml") to improve maintainability and reduce the risk of typos.

Suggested change

	if opts.registry == "jozu.ml" {
	if opts.registry == jozuMLRegistry {

May be this would work better if it was a url-to-label map that could be utilized for other registries.

I don't think we should start special-casing different registries to ensure we're showing the correct term here. On jozu.ml, your username is your email -- the credentials you use when logging into the service.
