[google_sign_in] Support setting the nonce for each authentication

[BinnyBipin]

I am implementing (SUI) zk login with Google Sign in. For which we need nonce. Now when the google sign is initialized once and the nonce is set, upon logging out and reinitializing with new nonce doesn't work.

In the doc it is mentioned Clients must call this method(Initialize) exactly once.

If this is the case how could i possibly pass a different nonce for different account. Need Help!

..initialize(
clientId: kIsWeb
? AppConstants.googleServerId
: AppConstants.googleClientId,
serverClientId: kIsWeb ? null : AppConstants.googleServerId,
nonce: nonce,
)

Please check the migration guide to see if it helps although I am not sure about below case.

This isn't currently possible. The reason the API was designed this way is that the web API sets the nonce as part of initialization. In theory we could re-set it by re-initializing on every call, but that would add some complexity.

Could you elaborate on the use case? Are the nonce values coming from an external system you don't control?
