Update the used Flutter version to 3.16.5 and the used packages to their latest version. The Supabase package contained some breaking changes: - `functionUrl` is not exported anymore, so that it must be generated by ourselfs - `Provider` was renamed to `OAuthProvider` - The `signInWithApple` method was removed and is now implemented by us via the `sign_in_with_apple` package. We also renamed the `DesktopLoginManager` to `DesktopSignInManager` to use the same naming as in other places of the app, where we are always using sign in and not login.
