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.
