For internal use or for those programming around the Google API. Returns a token pre-processed with [httr::config()]. Most users do not need to handle tokens "by hand" or, even if they need some control, [gar_auth()] is what they need. If there is no current token, [gar_auth()] is called to either load from cache or initiate OAuth2.0 flow. If auth has been deactivated via [gar_deauth()], gar_token() returns NULL.
