For dovecot 2.4.0 onwards the configuration file has changed instead using ssl_server_cert_file

There are several other changes to these config file names aswell.

Dovecot 2.4.0 was released 24 Jan 2025.

The latest dovecot config version in ssl-config-generator src/js/configs.js is dovecot 2.3.21

@EAJ-EAJGlobal: Would you like to try to put together a patch and PR for the changes needed for Dovecot 2.4.0?

This provides more context for the incompatible changes: https://doc.dovecot.org/2.4.0/installation/upgrade/2.3-to-2.4.html

I have opened a draft pull request to update syntax for dovecot >= 2.4. Would appreciate a fresh perspective on the changes.
