OpenID Connect Error on iOS

[bjoernch]

@james I saw this issue is already fixed and you can just add "org.traccar.manager:/api/session/openid/callback" as a Callback URL which is great, but not yet reflected in the official documentation. It would be really useful to add this to the OpenID Connect documentation at https://www.traccar.org/openid-sso/ — especially the note about adding org.traccar.manager:/api/session/openid/callback as a second redirect URI to support iOS.
