[google_sign_in] Throwing deprecation warnings and using outdated SDK and dependencies #91221
Description
Right now google_sign_in is throwing several deprecation warnings about embedding v1 like the following.
With #91069 in mind, i think the best action would be to remove all reference to embedding v1.
Besides that this package is targeting old dependencies and SDK and it should be updated.
