Provide methods to achieve auth related actions (sign-in, sign-out)

[MatteoGauthier]

Currently, the authClient methods to sign in / sign up / etc.. are not immediately updating the session query data, I think methods accessible from a hook can simplify the invalidation / refetch process.

Maybe a useAuthActions hook

Yea I could make this hook. For now you can just call refetch on useSession to refresh it. But that’s all the hook would do
