OIDC UserInfo acquisition is enforced if UserInfo is injected

https://github.com/quarkusio/quarkus/wiki/Migration-Guide-3.10#oidc-userinfo-acquisition-is-enforced-if-userinfo-is-injected
Starting from Quarkus 3.9.0, quarkus.oidc.authentication.user-info-required property is now automatically set to true when quarkus.oidc.UserInfo is injected in the REST endpoint.
It may cause OIDC tenant initialization failures if you use more than one OIDC tenant to secure the endpoint and some of these tenants do not support UserInfo. In such cases, set a tenant specific quarkus.oidc.<tenantid>.authentication.user-info-required property to false.
