Spring Authorization Server supports OpenIDConnect.
I want to support OIDC endpoints in springdoc too.

reference: https://docs.spring.io/spring-authorization-server/docs/1.0.1/reference/html/protocol-endpoints.html#oidc-provider-configuration-endpoint

The latest version of Spring Authorization Server has more logout endpoints, but this time we will support the one as of 1.0.1.
