feat: Fetching user metadata by oidc manager

[s681562]

Description

I wish seeing more fields in OidcUser, for instance user metadata like phone number.

Clearly describe what you are looking to add. The more context the better.

Requirements

• Checklist of requirements to be fulfilled

Additional Context

Such fields like 'profile.attributes.phone' or 'Telefon' I wish to fetch or access via OidcUser or via OidcManager.

Add any other context or screenshots about the feature request go here.
