With this commit: - The information about ScyllaDB Enterprise OS support is removed from the Open Source documentation. - The information about ScyllaDB Open Source OS support is moved to the os-support-info file in the _common folder. - The os-support-info file is included in the os-support page using the scylladb_include_flag directive. This update employs the solution we added with https://github.com/scylladb/scylladb/pull/16753. It allows to dynamically add content to a page depending on the opensource/enterprise flag.
