Fix the problem of NoSuchMethod error of auth provider (#66)

Current plugin cannot work due to removal of method `run.halo.app.infra.SystemSetting.AuthProvider#enabled` in Halo 2.20.0. This PR fixes it by using new alternative method `run.halo.app.infra.SystemSetting.AuthProvider#states`. /kind bug ```release-note 修复无法在 Halo 2.20.0 中正常登录的问题 ```
