Create offline sessions if approval is skipped

[nabokihms]

Overview

Offline session is not created if the skip approval option is toggled. In this case Dex looses connector data and cannot refresh tokens.

It leads to the different refreshing errors in logs like:

{"time":"2024-11-06T10:19:31.541474938Z","level":"ERROR","msg":"failed to refresh identity","err":"gitlab: failed to get refresh token: oauth2: \"invalid_grant\" \"The provided authorization grant is invalid, expired, revoked, does not match the redirection URI used in the authorization request, or was issued to another client.\"","client_remote_addr":"10.244.28.54","request_id":"8e46b1aa-3bd2-4ef1-a844-ad0db91dbc1e"}

What this PR does / why we need it

This PR adjust the part of the code to make it creating and updating connectorData when it is needed avoiding refresh errors.
