Fix auth-server-url for keycloak

[oliv37]

When using quarkus.oidc.auth-server-url=https://host:port/auth/realms/{realm} with keycloak , I get the following error :

io.qua.oid.dep.dev.OidcDevConsoleProcessor] (build-17) OIDC metadata discovery failed: {"error":"RESTEASY003210: Could not find resource for full path: http://localhost:8081/auth/realms/test/.well-known/openid-configuration"}

The property value should be https://host:port/realms/{realm} instead of https://host:port/auth/realms/{realm}

Makes sense now that Keycloak 20.0.1 is Quarkus based
