Describe the bug

Some certificates are expired in previous branches (22 and 24). The certificates were updated for upstream in this commit: https://github.com/keycloak/keycloak/commit/e9c9efc3f4dac20cf6a791fd3efaa246612038bd. But I forgot of backporting to previous branches. As the commit should be stripped to remove the BC upgrade I'm opening this issue to assign an issue for the PRs.

```
