iOS google app ownership should be transfered

[azinman]

Currently the bundle identifiers for apps that use Google Sign In (dice roller, todos, login example) all start with v.io.zinman to serve as a reminder that I created the apps rather than a vanadium-owned email. I did share the edit role on these apps with others in the vanadium team, but it's not clear what the "official" way is.
