Point mod_auth_openidc to latest release if upgrade is requested (Rocky 8+9) (#95)

Point mod_auth_openidc to latest release if upgrade is requested with `UPGRADE_MOD_AUTH_OPENIDC`, in order to address a potential security issue (CVE-2025-31492) as described in the associated release notes at https://github.com/OpenIDC/mod_auth_openidc/releases/tag/v2.4.16.11 It does NOT sound like we are affected, since we don't adjust the mentioned `OIDCProviderAuthRequestMethod` setting in docker-migrid or migrid. Still, it may make sense to have the option to easily upgrade with the security fix and other recent bug fixes included. **NOTE**: we cannot generally upgrade on CentOS 7 as well, since upstream no longer provides the corresponding packages there without a commercial support contract.
