OIDC will request UserInfo and TokenIntrospection even if they are cached
### Describe the bug

Users have discovered that even if OIDC caches UserInfo it will still request UserInfo remotely, thus making cache ineffective as far as the performance savings are concerned. Same applies to caching TokenIntrospection

### Expected behavior

If UserInfo is required and the cache is enabled then repeatedly calling the Quarkus endpoint with the same token should result in a single remote UserInfo call only until the cache entry has expired or the cache limit has been reached.
