[Feature]: `Get/Update-AzConfig` make `LoginExperienceV2` a boolean like the rest

[o-l-a-v]

Description of the new feature

Make the AzConfig property / setting LoginExperienceV2 a boolean like the rest. And maybe change the setting name from LoginExperienceV2 to EnableLoginExperienceV2 to make it uniform. As far as I know this setting only got two options anyways?

Tricky part is backward compatibility.
