Store Google OAuth access and refresh tokens in user properties after sign up

Dear @hsluoyz , I want casdoor to store google credentials (access_token, refresh_token) in user properties attributes after a successful "sign up with google". How can I do this? Is this supported? If not, can I send a PR for it?

I want those credentials stored because I want to set Google Meet scopes and later I need to call GMeet APIs on behalf of the user

@sesota can you send a PR?

Sure. Sent: https://github.com/casdoor/casdoor/pull/2999

Add the code to your google only, don't mess with other providers
